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, Card 113 Laminated Plastics on the Basis of Glass S/191/60/000/002/008/012 Fiber. Communication V. Contact Method for B027/BO58 the Forming of Large Products From Polyester Glass Plastics 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.

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 Card 1/3 97653 Laminated Plastics on the Basis of Glass S/191/60/000/003/002/013 Fiber. Report 6. Effect of the Degree of B016/BO54 Polycondensation of Polyester Resins and of the Concentration of Terminal Groups on the Properties.of Resins and Glass-reinforced Plastics 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 Card 1/2 87655 Laminated Plastics on the Basis of Glass Fiber. S11911601000100310081013 Report VII. Glass Textolite on the Basis of B016/BO54 Polyvinyl.Butyral 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.

A Polyester Binding Agent for Glass-reinforced Plastics PERIODICAL: Plasticheshiye massy, 1960, No- 4, pp. 9-12 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 Card 1/3 87922 Laminated Glass-reinforced Plastics. S11 9 V60100010041003101 5 Report VIII.

Information IX, 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 Card 1/2 Laminated Plastics on Glass Fiber Basis.

Hardening of Some Resol Resins B0041bO64 Used in the Production of Glass-reinforced Plastics and Other Laminated Plastics 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 (resin 1: 5.5 - 8.0 %, resin 0 15.5 - 16.4 %), the difference in the hardening rate, determined by this method, was 15 - 20 seconds only. determined according to I.

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.

Dyeing of Polyester Glass- reinforced Plastics 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 Card 1/p Glass Fiber Laminates. 12. Dyeing of Poly- S/191/60/000/003/003/010 ester Glass-reinforced Plastics B013/BO55 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.

A New Binder on the Basis of Unsaturated Polyester Resins With Addition of an Organophosphorus Compound 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 Card 112 88547 Laminated Plastics on Glass Fiber Basis. S/191/60/000/011/003/016 Report 13. A New Binder on the Basis of BO13/BO54 Unsaturated Polyester Resins With Addition of an Organophosphorus Compound 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.

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.

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.

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.

Gelling with C+ B started in 1-3 hours in the polyester samples; the corresponding ~IJP(c) W W/RM Card IAZ ---ULC: 678.6741410 =9:678.744] :678.o44.8 L 38508-66 ACC NR- AP6018123 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 2 resins have improved properties. Orig, art. has: 8 fia~~ es and 1 table.

ORG: none TITLE: Moisture resistance and chemical stability of unsaturated polyester resins modified with colophony SOURCE: Plasticheskiye massy, no. 9, 1966, 40-42 TOPIC TAGS: solid mechanical property, polyester plastic, synthetic material, phys chemistry property, stability constant 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.
