Communication V. Contact Method for the Forming of Large
rroduots From Polyester Glass Plastics
PERIODICAL% Plasticheski7e massy, 1960, No. 2, pp. 29-35
TEXTs The authors describe contact forming of large products from poly-
ester glass plastics as the simplest and most economic method, since
hardening of unsaturated polyester resins is possible by addition of
certain admixtures at room temperature. Molds from metal or glass plastic
are best suited for the process; positive molds produce a smooth inner
surface and negative ones a smooth outer surface; there are also
multiple-part molds to facilitate the removal of complicate shape products;
electrically heated molds are also used sometimes. In order to facilitate
removal of the products from the molds, various separating agents are
used, such as films from certain polymers (polyamide film RK-4 (PK-4)),
most frequently$ however, alcoholic-aqueous solutions of polyvinyl alcohol,

but also mastic and pastes on wax- or paraffin basis. Various decorative
coatings from resin with hardeners are applied to the mold by aprayer or
brush. After the coating has gelatinized, the shredded glass fiber.and
resin with hardeners are attached by spraying machine or spray gun. When
using glass fabric or glass mats, resin with hardener and accelerator as
well as glass filler are laid in layers and each layer is rolled. The
processing time for the resin of the type ITH -1 (Pn-1) with active material
and accelerator amounts to 40 to 90 min; inert fillers in powder form are
sometimes admixed to increase viscosity and hardness. For the contact method,
various types of glass fabrics may be used, which must previously be cut
to shape, a larger edge having to remain, which facilitatee removal from
the mold. The glass fabric cut to shape is connedted in the form of butt
joints which must be covered by the next layer. Best durability of the
products is obtained with a content of 40 to 5qo polyethylene resin in
glass plastic and 60 to 7Wo in glass mats. Smaller products are removed
from the mold by hand and larger ones by machine, and undergo machine
finishing. If a product consists of several parts, the best way of
assembly is the simultaneous use of glued and mechanical joints. Subsequent

repair work is easys' it'is sufficient',to polish the~defect with emery
paper and to apply some layers of-resin-saturated glass mat or glass fabric.
When working with P;olyethylene resins it must be considered that.their
evaporation leads to irritation of mucous membrane and thus a sufficient
ventilation of the rooms is -absolutely"necessary;' rubber gloves or skin-
protecting cream'are required. These resins.are'also inflammable so that
fire extinguishing equipment should be available in the plant. Due to
danger of explosion,'-hidrogen peroxide ind'the accelerator must in all

Effect of the Degree of Polycondensation of Polyester
Resins and of the Concentration of Terminal Groups on the
Properties of Resins and Glass-reinforced Plastics
PERIODICAL; Plasticheskiye massy, 1960, No. 3, PP. 9-12
TEXT: The authors report on their studies of the effect of the degree
of polycondensation and acidity of polydiethylene glycol maleinate
phthalate (3 : 2 : 1 ) on some properties of the solid solution of this
resin in styrene M-1 (PN-1), as well as on the properties of glass-re-
inforced plastics when using this resin as a binder. The authors had
conducted the synthesis of the,resin, and had published it earlier to-
gether with indices (Refs. 1,2). They found that polyester resins of
different polycondensation degrees (acid number 20-100 mg KOH g) in the
presence of industrial isopropyl benzene hydrogen peroxide(Wland
HK (NK) accelerator (8%) gelatinize faster with increasing molecular

weight and decreasing acidity. This phenomenon was ascribed to: 1) ex-
tension of macromolecules of the unsaturated polyester increases the
probability of copolymerization with styrene; 2) increased acidity in-
hibits the dissociation of the hydrogen peroxide; the free carboxyl
groups of the polyester have a deactivating effect; 3) possible isomeri-
zation of maleic to fumaric acid (Ref-5). The authors keep on studying
this problem. Simultaneously with the acceleration of gelatinization,
the polyesters solidify to a higher degree, and their hardness and
Tesistance to water increase.. Further, it is shown that the mechanical
strength of resins increases with increasing molecular weight of the
initial polymer. This effect also prevails in T-1 (T-1) glass-rein-
forced polyester plastics. Tensile strength and resistance to static
bending are practically independent of the degree of acidity and poly-
condensation of the binding resin. It is noted that the dielectric
properties of glass-reinforced plastics depend chiefly on water absorp-
tion. tan 6 for specimens with binding resins of an acid number of
70 mg KOH/9 is much larger than with resins of 43.3 and 28 mg KOH/g.

Class Textolite on the Basis of Polyvinyl Butyral
PERIODICAL: Plasticheskiye massy, 1960, No. 3, PP, 48 - 49
TEXT: The authors report on their studies of methods of producing glass
textolite from polyvinyl butyral (PVB) with glass fabric of the type
ACTT (61 (ASTT (b))las-a filler. They used A-type PVB, and found that
PVB embrittles at high temperatures, and loses its elasticity and solu-
bility. Also its impact strength decreases, whereas hardness and bend-
ing strength increasej At high temperatures, PVB decomposes, becomes
sticky, and its mechanical strength;decreases. This was ascribed to a
change in molecular structure, which changes from linear to steric with
numerous cross links (Refs. 20). In glass textolite, the PVB content
dropped to 4% after impregnating the glass fabric with an 16% PVB solu-
tion after drying at high temperature. Glass textolite was produced for

experimental purposes a) by molding at different pressuresand b) by de-
formation in vaouo. The authors studied the effect of temperature, PVB
content, and deformation pressure on the properties of glass textolite.
They found.that a change in the PVB content has no great influence on
the quality of glass textolite. A pressure of more than 45-50 kg/CM29
however, effects a decrease in strength with the use of most kinds of
resin, probably due to destruction of the filler. It is shown that with
the use of PVB a much higher pressure can be applied, without detri-
mental consequences, than with the use of other resins. Further, the
authors found that PVB glass textolite deformed in vacuo has a lower
strength than phenol glass textolite produced in vacuo. Experimental
results.show that the increased specific pressure endured by PVB
products improves their quality. The properties of PVB glass textolite
can be changed by additional heat treatment. There are 2 figures and
4 Soviet references.

TEXT: The authors descr%be polypentaerythrite dichlorohydrin maleinate
phthalate (PDP), which was synthetized for the first time. It was the
purpose of the study to widen the raw-material basis of polyvalent alcohols
for the synthesis of unsaturated polyester resins by using polypenta-
erythrite. In contrast with the inadequate methods known, the authors
proved that unsaturated polyesters with higher fire resistance can be
synthetized by using a chlorind-containing alcohol component. For the poly-
condensation they used pentaerythrite dichlorohydrin (PED), which is formed
by saponification of the reaction product of pentaerythrite and thionyl
chloride in the presence of pyridine. PDP was synthetized from PED b ad-
ding maleic acid and phthalic anhydride (molar ratio 1.0 : 0-5 : 0 U in

of-the total content of all components. After solidification, PDP mixed
with 1/5 styrene gives a product that is difficultly combustible and stops
burning after removal of the flamee The produpt from 70 parts b~ weight of
PDP and 30 units of styrene is stifl less combastible. PDP may be mixed
with methyl methacrylate at anyproportionp and its solution In styrene
(45 : 55) does not tend toward stratification, Its solutions are gelatiniz-
ed at room temperature within three hours in the presence of 6% 4SOpropyl
benzene hydrogen peroxide and q. of the accelerator H V(NK). This also
occurs within 15 minutes in the presence of Y. methyl-ethyl ketone pe-.r,--
oxide and 3% NK. From PDP and glass fabric T,, (T,), the authors produce-1
samples of self-extinguishing glass textolitep which are superior to the.
product from styrene resin TrH-1 (PN-1) with respect -to their most important
mechanical and insulation properties. The authors prepared a test sampl_~_

Hardening of Some Resol Resins Used in the Production of
Glass-reinforced Plastics and Other Laminated Plastics
PERIODICAL: Plasticheskiye massy, 1960, No. 5, PP. 12 - 14
TEXT: The authors discuss the optimum properties of a resin suited for
glass-reinforced plastics. They come to the result that the resin should
be comparatively little active until 1000C, at a temperature rise to
1500C, and more, however, it should quickly harden. The following samples
were tested: resin 1, a phenol-formaldehyde-resol resin; resin 2: a
phenol-formaldehyde-resol resin; resin 3: a cresol-formaldehyde-resol
resin, and resin 4: a phenol-aniline-formaldehyde-reso1 resin, Resin 1
was condensed in the presence of NH 3 + NaOH, the other samples in the
presence of NH3 only. The content of free phenol, melting point, and rate
of hardening were determined. The first method, i. e., the determination

of the rate of hardening on a plate of 1500C, proved to be unsuitable.
In spite of the considerable difference in the content of free phenol

hardening rate, determined by this method, was 15 - 20 seconds only.
determined according to I. Schef
The hardening rate was, therefore, iber
(Ref. 6): Impregnation of filtering paper with resin, heating to 10, .130~
or 1500C, and, after 20, 40, 60, 120, 180, and 240 minutes, determination
of the residual solubility in an acetone-alcohol mixture of '10. By this
method, the following results were obtained: 95.5 % of resin 1 be?,ame
insoluble at 1500C after 120 minutes, 94 % of resin 2 after 180 minutes,
87 % of.~resin 3 after 240 minutes, and 90 % of resin 4 after 240 minutes,
The rise in the percentage of resin having become insoluble at low
temperatures (1100 and 13000 shows a course characteristic of the respn,-
tive type of resin. Therefore, this method is recommended for the dEtermi-

TITLEs Glass Fiber Laminates. 12. Dyeing of Polyester Glass-

PERIODICAL: Plasticheskiye massy, 1960, No. 9, pp. 11 - 15
TEXTt The present work deals with the dyeing of glass-reinforoed
polyester plastics and the dyes used for this purpose. The investigation
showed that polyester resins may be colored satisfactorily with azo-,
anthraquinone-, and triphenyl-methane dyes, phthalocyanine pigments, and
others. The results obtained with several vat dyes and direct dyes were
unsatisfactory. Inorganic pigments and dyes gave less brilliant hues than
organic colorants. The results of the investigation showed that most dyes
retard the gelling process. This retardation, however, is comparatively
insignificant so that the properties of the hardened resin are hardly
affected. To obtain well-colored products, the resin is generally applied

in two thin layers, a coat thickness of 0.4 - 0.7 mm being advisable. I-i
practical use, structural glasti-reinforced plastics are often exposed to
sunlight. This necessitates the use of specially light-fast dyes. The
color stability of samples was tested both in the laboratory under a
ITPK-4 (PRK-4) quartz lamp and in open air, on roofs in Leningrad and
Moscow. The following facts were established: 1) Polyester resins turn
yellowish under suzili-ght. This is particularly noticeable with the
lighter shades. 2) InorFunic pigments are the most light-fast. Direct
introduction of the dye or pigment is the most expedient way of dye-ing,
but cannot be repeated. It is often the case, however, that the color of
some structural part dyed in this manner must be renewed owing to damage
or fading. This can only be done by applying enamel or oil paint. Some
recipes for decorative units are given. According to destination,
structural glass-reinforced plastics may be exposed to salt water,
petroleum products, mineral oils, alkaline, and acid media. The coloring
of plastics was stable for 4500 h in sea water, 3 h in boiling water,
3000 h in mineral oil, 24 h in 10% H2 so 41 and 24 h in 2% NaOH. There are
5 tables and 5 non-Soviet references.

PERIODICAL: Plasticheskiye massy, 1960, No. 11, pp. 9 - 10
TEXTt The authors studied the possibMty of producing incombustible resins
with the use of dichloro-diethyl ester of vinyl phosphinic acid (DE).
Dichloro-diethyl ester was synthesized by Ye. L. Gefter. Experiments with
the use of DE with usual resins gave no satisfactory results. Its use with
chlorine-containing polyester resins is much more promising. The effect of
organophosphorus admixtures on the properties of chlorine-containing resin
is shown in Table 1. Hence, it appears that with addition of small DE
amounts the properties of resin remain practically-unchanged except for
the gelation rate. Some physicomechanical properties of glass-reinforced

plastics from chlorine-containing polyester resin, with and without DE
addition, are given in Table 2. The refractoriness of samples of glass-
reinforced plastics was tested by exposing the sample to an open flame
for a definite time, and - after removal of the flame - determining the
duration of independent burning and glowing of the'sample, as well as the
loss in weight (Table 3). Combustibility of glass-reinforced plastics was
little reduced by the addition of DE to the general-purpose resin of the
type nH-1 (PN-1). On the other hand, an introduction of small DE amounts
into chlorihe-containing resin, which is only slowly .-.extinguished after
removal of the flame, warrants the production of hardly combustible glass-
reinforced plastics. There are 1 figure, 3 tables, and 3 references:

TITLE: Self-extinguishing unsaturated polyester resins
PERIODICAL: Plasticheskiye massy, no- 5, 1962, 10-15
TEXT: Self-extinguishing polyesters were obtained by: (1) special
admixtures, (2) chemical modification. By adding Sb 20 3 (14-3~'-) and PVC
resins (6.7-7.9-iw-) to TTH-1 (PIT-1) resin, glass reinforced plastics made
therefrom on the basis of glass fabric T, (Ti), showed worse physical-
mechanical properties, reduced impact strength, increased viscosity and
opacity. Modification was based on the principle of introducing chlorine
atoms into the polymer molecule. Ethylene glycol was polycondensed with
malaic and totrachlorophthalic anhydride (ratio 1-1-.0,5:0-5) in the melt
at *i6o, 160 and 2000C in inert gas atmosphere. The reaction started at
13-50CP the acid number of 35-40 mg KOH/9 was reached after 4-5 hr at 2000C,
which proves the high reactivity of tatrachlorophthalic anhydride. Poly-
condensation was a reaction of second order. Its rate constantain

solid polycondensate is soluble in atyrone, methyl methacrylate and poly-
ester acrylates. A 3W6 styrene solution of polyethylene glycol maleinate
tetrachlorophthalate was best. Methyl-ethyl ketone peroxide combined with
cobalt naphthenate and the redox system p-benzoyl peroxide-dimethyl aniline
served as hardeners, Addition of Sb 203 increases the fire-resistant
quality.of the resins and does not change the physical-mechanical
properties of glass reinforced textolites produced from them, which
correspond to those produced from PIN-1 . Moreover, ethyleneglycol %Tas

hydrophthalic anhydride (1) at a molar ratio of 1.1:0.5:0.5 and 1800C.
The reaction was here " 3.88 9-mole-i%min-l. The condensate is a solidp

sought. Replacement of ethylene glycol by diethylene glycol and increase

vacuo and molded glass textolite differ in that the 61/10-veraus-tempera-
ture curve for the latter shows irregularities above 1009C, due to
after-hardening of the resin and loss of volatile components (the loss
in weight being greater than with vacuum-shaped textolite). Therefore
vacuum-shaped glass textolite offers higher heat resistance and
mechanical strength. Glass textolite heated to 300 OC and cooled in the
exsiccator showed constant relative elongation owing to the elimination
of moisture. The bending strength of vacuum-shaped glass textolite after
heating to 3000C rose by 15% to 2000 kg/cm2, at 3500C by 10% to
1900 kg/cm2. The bending strength decreased above 4000C. There are

than that of,EG, and that the activity of the anhydrides in reactions with
BCNPD decreases In the order MA is greater than CA Is greater than TCPA. Poly-
esters synthesized from BCMPD,, E)G, DEG,, MA, CA,, and TCPA in various molar

ABSTRACT: new method for the synthesis of unsaturated polyesters having a regular
structure was developed in a study constituting an extension of a previously
published work (Avt,. avid. No 170666; Byull. izobrs, No. 9. 1965). This method
consists of a-two-stage synthesis. The first stage involves the synthesis of the
diester of glycol.and an unsaturated acid or of a mixed diester of saturated and
unsaturated acids by the addition of dicarboxyacid anhydrides to glycol. The
second stage consists of condensing the acid diester of glycol with the same or a
different glycol in the mole ration of 231. A schematic for the vulcanized or
hardened products of the first and second stages respectively is presented as

t
properties of Polyethyleneglycol-maleinateadipinate copolymeralls rized by a two-
stage condensation were determineds and the results tabulated. s concluded that
an increase of the'styrene in the initial solution from 40 to 50% increases the
elasticity and tensile strength of the polymers* This conclusion is corroborated by
previously published work by the authors on the properties of the products of the one-

ABSTRACT: The effect of vanadium pentoxide as an accelerator in an
oxidation-reduction curing system for the copolymerization of unsaturate
polyesters with different monomers was investigated. The study was
conducted using resins based on polyethylene glycol maleinate
hexachloroendomethylenetetrahydrophthalate blended with polyester acrylate
TMGm3i r with polydiethylene glycol maleinate phthalate. Resins were
cured with cumene hydroperoxide (C) and 0.25 and 0.5% solutions Of V205
in acid phosphate (accelerator B). The gelling rate was affected much
more by change in concentration of B than of C. Gelling with C+ B
started in 1-3 hours in the polyester samples; the corresponding

induction period at room temperature for C tNK (Abstractor's note--NK no
defined, probably cobalt naphthenate) was several days. The C+B system
gives a harder, more heat stable.lightly colored non-sticky glassy
product. If resins made with C +Pare heat treated for 3 hours at 809C
their hardness and heat stabilityVare higher than for room temperature
cure. Gel formation is slowed down in a.3-component system of C-f-B+ NK.
Optimum hardness and heat stability are obtained if about 0.5 parts by
weight of NK is used per 100 parts of resin. Unsaturated polyesters can
be cured at room temperature with systems containing V 0 resultant

ABSTRACT: Moisture resistance anc ion stability of two commercial resins mo&-
,~oxidat
fied with coephony, resin PN-10-Pa copolymer of an unsaturated ester with styrene and
resin TGM-3- (a copolymer of an unsaturated ester and polyacrylate)land some glass
lamina~~te~ssed on these two resins were investigated. TRUE pnysica properties oF the
colophony-modified resins are tabulated. The tensile strength of the colophony-modi-
fied resins and the glass-laminates based on them was practically unaffected after
holding in water or 25%-sulfuric acid for 7-360 days. In general, the addition of
colophony was found to be beneficial with respect to water resistance and chemical
stability of the unsaturated polyester resins. Orig. art. has: 1 figure and 3 tables.
