ABSTRACT: The thermoelastic propertiea of the n1tural caoutchouc were
investigated according to the method of tile adiabatic expansion
in tile cycle: expansion- shrinking. The deformation velocity
amounted to loo % per second. The patterns differed by vulcani-
zation mode 'and the kind of the dispersed filler. It is shown
that the initial stages of the extension in the case of non-
filled (X,4,5) and filled (A t@,1,8 to 4) rubbers are character-
ized by a heat emission equivalent to 'tile deformation work.The
further deformation is accompanied by an emission of the surplus
heat effected by the crystallization of the rubber. Furthermcre
it in shown that tha beginn of crystallization and its degree de-
penda in the case of a given prolongation oil the vulcanization
process as well as on tile nature of the dispersing filler. Rub-
bers of greater inflexibility crystallize not so well. The active
filler- and the channel soot supports tile crystallization to a
greater extent than chalk and silica gel. A deformation velocity

remento without additional measures. It is determined that the
mistakes in the quantitative analysis of the processes in rubbers
in the case of adiabatic extension are connected with the igno-
rance of the real amount of the specific heat and with the in-
exactness in the determination of the prolongation in the case of
shrinking which is especially essential. There are 5 figures and
5 Slavic references.

ABSTRACT: The thermoelastio properties of rubber produced from butyl.-Caouto
chouc according to the method of abiabatic extension were inveatio
gated. The authors show that in the case of non-filled rubbers the
begin of crystallization occurs at an extension degree of X>7.
Vulcanization products with a gas:-soot filling do not crystallize
at a deformation of up toAc*.,6. The initial stages of deformation
are accompanied by a cooling-down of 1OC. The analysis given here
made it poasible to prize the regularities in a rubber produced from
butyl-caoutchouc without filler in the case of extension as well as
to determine the lack of crystallization processes in rubbers with
soot filling up to 9-fold extension.
There are 1. figure and 3 Slavic references.

TEXT: The clausical theory, which in based on thit ansumption of central
forces acting between the molecules, in not able -:o de!3cribe many
phenomena, for example, the propagation of short saves of sound. In order
to be able to explain certain anomalies in the dy-amic elasticity of
plastics, the authors have developed a phenomenol:-gical theory of
elasticity of complicated media, taking into acco-;@nt the rotatiural
interaction of particles. In this theory. the par--.iQles are regaided
not as points, but as extended objects whose diatance from each cther
is equal to their diameter. The action of the par-;icles on one aiiother
is described by a system of forces and moments. A:.-cordinE; to the

TE'XT: The reduction of the molecular weight of polymers in mecha-lical
crushing observed by various investigators induced the authors to carry
out the following experiments: Chips were cut off on a turning lathe from

quence of the destruction on the surfacen newl,-, formeJ during cutting
(Fig. 2); a "destruction depth" g = (A[jYffl)-h, -Ahere h is the t-,ick
ness of the chips. Fig. 3 shows the function g . pj(h) which is no; linear.
Further, the authors experimentally determined g/h L[J]MLas a *"unction
of the cutting speed v (Fig. 4), and the funct ion g fj h77) (Fi,@- 5).
The latter yielded a family of curves with linear initial sectionj having
the same tangent. The authors therefore assume diffusion processe3. They
tried to find a universal curve g1h - f(Y-1/@v@h . The destruction d!pth
should be determined by the diffusion coefficient D. Fig. 6 shows that no
universal curve but another family of curves was obtained. The value of
D was found to be jo-4 CM2 /sec which does nP a5ree either with the
order of magnitude of the gas diffusion (10- CM Isec or with thit of the
temperature coefficient of heat conluctivitj (10-@ cm@/sec). Thus, the
destruction processes do not only depenfl on the rupture of chemicil bonJs

TITLE: Apparatus for Thermomechanical Investigation of Polimeril by
the Method of Monoaxial Elongation
PERIODICAL: Zavodakaya laboratoriya, 1960, Vol 26, Nr 1, pp 100 - 102 (USSR)
ABSTRACT: An apparatus (Fig 1) was designed for testing thin uniformly
heated plastic samples under uniform stress (at monoax1al elonga-
tion). A temperature range of -150 to +2700 at heating- and cool-
ing rates of 2 to 60OC/hr, loads of 20 g to 3 kg, and 3ample
elongations of 0-50 mm can be applied in the test. Sam;)le strips
having a test length of 50 mm, a width of 2-5 mm and a thickness
of 0-05 - 0-5 mm are tested. The apparatus contains a levice for
uniform sample elongation by means of an electric deformation

primary element, a thermostating unit, to control heat-.* *ng and
cooling rates, and a unit for recording sample deforma,-.ion and
temperature. At the one end, the sample is clamped to it fixed
holder, and at the other to a holder attached to a wir4i rope.
The horizontal wire is guided over a pulley, the pan w*.th the
weights being attached to the depending end. The pulley has a

adjusted as rheochord primary element of sample deformition. The
sample itself is placed in a horizontal cylindrical chimber
which can be heated by a heating element or cooled by liquid
nitrogen. The heating element is fed by an autotransformer of
the type LATR-1 and the nitrogen is circulated bya UYT pump.
Commutation of the current in the heating element and switching-
on of the pump are effected by means of an electronic EPV-01 71
potentiometer Furthermore, an RSP rheostat, SD-2Alectric
mot-or, KVT-6 otentiometer, LS-12'rectifier, PP potentiometer,
and an 1-4-94 VImicroammeter are used. The circuit scheme applied
to recor sa@mple deformation and temperature is illustrated
(Fig 2). Thermomechanical curves for crystalline polyethylene
terephthalate obtained by means of the apparatus desexibed above
by applyinq various loads and a temperature increase cf 0.90C/min
are given (Fig 3). There are 3 figures.

TITLE: Determination of the Surface Cracking Resistance of
Transparent Plastic Materials on Wedge-ehaped Sasplea
PERIODICAL: Zavodskaya laboratoriya, 1960, Vol. 26, No. 12,
pp. 1390-1391
TEXT: The surface cracking resistance may be characterized by aeane of the
tensile stress, at which the first visible cracks occur within a given time
interval after application of load, or by determining the surface under
stress in the case of a pure banding teat, at which the first cracks occur.
A further possibility is offered by the occurrence of cracks on the surface
of plastic materials sometimes after having been wetted with oreanic liquids
For being able to judge the surface cracking reaistancep these nethods are,
however, unsuited. V. R. Regell (Ref. 7) suggests the curve v, ; f(c), i.0,

cracking resistance of plastic materials. In the present paper, i% is also
suggested to characterize surface cracking resistance by means of the rela-
tion To . f(c), where the sample has the shape of a truncated wedge. The
cracks at first occur in the narrow sections of the sample, and only later
on the broader sections. A cracking front forms, which gradually ohifts
from the narrower to the broader sections of the sample. The vidth of the
sample at the place of the "front" is periodically measured, the -;ime since
the beginning of the stress is noted, and from the thickneag of the sample
and the tensile force, the tensile stress corresponding to 1 0 is oalculat-
ed. The wedge-shaped samples (gig. 1) were sawed with a circular iiaw. The
ang,le of the wedge was about 5 , the maximum width of the sample iiaB
0-9 mm, Lind itu minimum width 3 to 3.5 aim. The thickness of the sampled
was 1-4 mm, and their full length 55-60 mm. Before the experiment.j were
made, the samples were heated to a temperature, which was higher by
10 - 20 0 than the fusion point of the given material. In the case of the
shape of the samples selected, the stress dropped from the minimun to the

PERIODICAL: Fizika tvardogo tela, v. 3, no. 1, 1961, 286-288
TEXT: It was the purpose of the present paper to study the electrical
ageing of titanium-containing ceramics by means of electron paramE.gnotic
resonance (epr). The investigations were carried out with capaci,;or
ceramics (87% T102, 5% Zr02, 2% BaC03, 6% A1203, and 6% Sio paste, burned
in the usual manner@; the specimens had the shape of tubes @28 mm long,
wall thickness 1 mm) and were partly electrically aged (1600C, 70C v
constant voltage)o The aged specimens were denoted by Ka, and thcee lot
in their original shape, by Koo For the investigations, an epr radio-
spectrometer with h-f modulation (I Mc/sea) of the magnetic field wae
usedl the epr signal was recorded by a recorder in the form of the first

derivative of the absorption curve. In the case of a fixed frequency of
the shf generator of 9300 Mo/sso, the field could be varied between 1000
and 4000 gauss. At 3000%j no difference could be found between the epr
spectra of Ko and Kai in both cases only 1 weak broad line (with 9=,.4.14)
van found. Therefore, all further experiments were carried out at T70K.
At this temperature, Xo showed a complex spectrum between 1000 and 4000
gauss; the spectrum of Ka was similar, but the lines with g= 1-97 and
1-93 were 1-5 times more intense, This part of the spectrum was mo-re
accurately investigated. During ageing, the concentration of
paramagnetic defects increased, and the electrical conductivity was
100-1000 times increased. An attempt is now made to find out why, Ln
spite of this considerable increase of conductivity, the intensily of
epr signals increased only 195 times- The opinion is widespread th,it
ageing of titanium ceramics is related to a reduction of titaniuml ihue,
Ko ceramics, which had been chemically reduced in different ways, wore
investigated. The degree of reduction was determined from the time for
which the specimens had been heated in CO at 9000C. After having bven
heated for 10 minutes in CO (KO-10), Ko had an epr spectrum which wE.9

exactly the same as that of the original Ko. With further reducticn,
intensity and width of the line with 9':-.1.93 increased, the line with
9 =1.97 remained unchanged in contrast to the effect produced by
electric ageing. After 60 minutes of reduction (KO-60) the line with
gtO-93 was so broad that it overlapped that with g,=1.97. The
concentration of paramagnetic defects in Ko-60 was higher by 3 orders of
magnitude than in Kof Thus, in the case of chemical reduction, only the
concentration of 1 type of paramagnetic defects is increased, in
electric ageing, however, the concentration of 2. In the pure com;onents
of the ceramics, no eEr signal was found, not even (T102) in the case of
irradiation wit h 7.10 r y-radiation from Co6o. The authors thank 1. Ya.

Effect of the molecular weight on the strength of
oriented amorphous polymers
PERIODICALs Vyaokomolekulyarnyyo noyedineniya, v. 3, no. 2, 1961,
215 - 222
TEM It was the purpose of the present work to study the effect of the
molecular weight of criented polymers on their strength in that range of
molecular weights in which the strength of isotropic polymers is i1o longer
affected. Stressetrain curves of oriented polymers also had to b@y plotted.
Pol vinyl acetate (PVA)g polymethyl methacrylate (PMUA), and pOly3tyrene
(Ps@ were used for the experiments. From the solutions of these Dolymers
films were deposited on glass plates and then dried in the vacuum for
3 - 4 days; the temperature was gradually increased up to 900C f3r PVA
and 1500C for PS and PMMk. The molecular weights were viscosimetrically
determined. The softening temperature was determined by plotting the

thermomechanical curves. Strips of 4 mm width and 10 mm length of 100 -
- 15Nk films were subjected to preparatory drawing at increased tempera-
tures. The ratio A between elongated specimen and initial length was bet-
ween 2 and a maximum of 200 - 300 for PVA, and 15 - 16 for PMMA. After
drawing the strips had a thickness of 10 - 15 and 50 - 60@L , wkich was
optically determined with =14)8-1 (IZV-1) apparatus; their width amoun-
tea to 0.6 - 2.5 mm. The stress-strain diagram wa8 taken of a 10 mm strip
of specimens thus treated. A table gives the data of the specia.ena
studied, and the experimental conditions. Fig. 2 shows the strtse-strain
diagram of PVA which consists of three sectionsta steep first scetion M,
~ flat central section (II) in which maxima may occur for PVA and PS, and
~ steep terminal section (III) leading to the break. The shape of the
curve depends on the elongation X. PWLA and PS showed the same behavior.
The upper part of Fig. 5a shows the breaking stress 6 b (aP in the Fig.),
and the lower part shows the breaking elongation E b (EP in the Fig.) as
functions of preparatory drawing A. Fig. 6 gives the tensile strength of
isotropic and oriented polymers as a function of the molecular -veight.

TITLE: Shook compression of rubbers
PERIODICAL: Fizika tverdogo tela, v. 3, no. 11, 1961, 3487-3494
TEXT: Some time ago, the authors developed a KC (KS) pendulum type
elastometer (ZhTF, 16, 4, 877, 1956). With this device strain data can be
obtained from cylindrical rubber specimens and compared with theoreiical
results. The shock-atreas signals as picked up by a piezo-quartz
dynamometer (L. A. Layus. VINTI, Peredov. nauchno-tekhn.i*proizv. opyt,
t. 32, 1958) are fed into an )Iio-l (ENO-1) oscilloscope. The force during

however, that resilience either does not chanpe at all or rises slightly

TEXT, A previous work (Ref. I - this journal, 1957,
No. 5, 86) described equipment for determining the dynamic
mechanical properties of rubber in the frequency range of
loo to 4 Ooo c.p.,s. It was shown that, in principle, the
apparatus could be used for loi.,or frequencies and this lins now
been done. Measurements of the shear modulus and tangent of
mechanical loss angle can now also be made in the frequency
range of 0.01 to 100 c,p,,s. The output of an ultralow-
frequency generator is amplified and applied through a resistance
to the coil of a vibrator, A peak voltmeter is used to nonsure
the voltage drop across the resistance which is proportional
to the stress applied to the specimen It al-go measures the

TITLE: Ways to develop a quantitative theory of vitrificition
PERIODICAL: Fizika tverdogo tela, V. 4, no. 12, 1962, 3403-34)8
TEXT: This is a critical survey on studies since 1936 on the relaxation
theory of the vitrification of amorphous bodies. It is shown tnat the
relaxation theory, although well known, gives only qualitative results,
and that systematic investigations of vitrification are lacking. To
develop the theory further, the following stu'dies are proposed:
(1) experimental investigation of rules governing property charges of a
substance during heat treatment, compression and elongation; (2) confirma-
tion that when a function of state is established this enables the behavior
of a substance under any course of treatment to be predicted; (3) explana-
tion of a kinetic equatlon on the basis of the general conceptJ.ons of
molecular relaxation. The equation of state

The weii,- of rubber has been studied at the Institute of Macromolecular Com-
pounds, Academy of Sciences USSR, with special equipment permitting 1) vis-
ual observation and cinemicrophotography of the phenomena ocaurring a:; a
smooth steel indenter slides back and forth on a rubber surface and 2) s, udy
of the effects of the number of indenter passes, contact pressure, and g kse-
ous medium. The experiments were conducted at room te mz@erature with
filled butadiene (CKB, CM ), butadiene-styrene.( CKC-30-A ), carboxylited
(CIM-30-1 ), Isoprene (natural, CHM ), and butyl rubbers and with unfilled
CKZ and nairit. Rubber wear was shown to be the re@ult of degradation.
The rubber surface becomes tacky, and the wear mezhanism is a contina-
ous rolling up and removal of this tacky surface layer. In some cases tle
presence of oxygen affects the nature of the wear: the wear of isopren(
rubbers in air was shown to differ from that in Ile. In air, it is accompanied-

by the separation of an oily liquid indicating the development of oxidatio-l, which'
is also observed in the case of CKC-30-A . Tile wear.processes of CM and
CKC-30-1 in air and in He are identical. It is also shown that the degradation
of rubber is not associated with the evolution of the licat of friction. Changing
the temperafure of the experiment affects the development of the process con-
siderably. For example, at temperatures above the softening point of poly-
methyl methacrylate, its wear is similar to that of rubber, but at lower tem-
peratures the wear is different: particles are chipped off of the unchanj:ed
material. The results of the study lead to the general. conclusions that -:he
wear of rubber is closely linked to the development of mechanochemical de-
gradation. BAO)
