TITLE: Stereoregularity and Optical Anisotropy of Molecules of
Polymethyl Methacrylate
PERIODICAL: Vysokomolskulyarnyye soyedineniya, 1960, Vol. 2, No. 8,
PP. 1176-1187
TEXT: The authors discuss the effect of stereoregularity of a polymer on
the physical properties of its molecules. They arrive at the opinion that
the measurement of optical anisotropy should be a sensitive method of
structure determination. In a previous paper (Ref. 29), they had proved
that isotactic and atactic polystyrene show considerable differences in
optical anisotropy. The present paper studies the effect of stereoregulari-
ty of the molecular chain on optical anisotropy in polymethyl methacrylate
(PMMA). The following Ph8fil samples were used: sample A, isotactic, vitri-
fication temperature TV a 500CI sample B, atactic, TV = 110 0 C; sample C,
syndiotactic,T Vabove 1100 C. Samples A and C were dissolved in benzene,

centrifuged, and decomposed by precipitation with hexane into fraa!tions
which showed a regular dependence of the Kerr effect on the electric field
applied., Next, the double refraction 6n in flowing benzene solution was
measured as a function of flow velocity. A linear dependence an = f(g)
was found. From the reduced double refraction dn/g 70 c (~o = Viscosity
of solvent, c = concentration of polymer), the following relation was cal-
culated by extrapolation of experimental data: fnj = lim (6n/g ~oc). Fur-

ther, the intrinsic viscosity 10 was determined. The segment anisotropy

Further, the optical anisotropy was calculated according to W. Kuhn (Ref.20):
a1 - a 2 = 7-5(all - aL). The following values wer found for (a,, - a.L).10-25
cm : sample A.- 3.3; sample B: between 0.19 and O-k4. Thus, the anisotropy
of molecules of the isotactic polymer is 14 times higher than thaz of the
atactid one. This increase in anisotropy on transition from the atactic
to the isotactic structure is explained by a change of rotation around
the stretching vibrations in the ester side group of PWAA. No differences
were.observed between the optical properties of the atactic (B) and syn-
diotactic (C) polymer. consequently, these samplea should have similar

Some methods of 8tudyinc flexibility and ahapo of macromolontilm
PERIODICAL: Leningrad. Universitet, Vestnik. Seriya fiziki i khimii,
no. 4, 1961, 'z9 - 63
TEXT: The author discusses methods of determining the size and the
flexibility of molecular chains. Such methods may involve light scattering,
viscometry, determination of diffusion coefficient, etc. Solutions of
polymers are particularly suitable for these kinds of measurements.
Ho'wever it must be noted that the molecular chains are riot branched..
Numerical data are given on the length and the equilibrium flexibilitd- of
a number of polymer chains. A molecular chain is more or less taneled and
has the shape of an ellipsoid when the polymer is dissolved. At the
moment the only experimental method of determining the asymmetry of such
molecular ellipsoids is that based on the birefringence of a flow of
polymer solution (dynamooptical effect) Structure, flexibility, and
optical anisotropy of the molecular chains are discussed and a few numerical

showed (e. g. in comparison with polystyrene) that the substitution of the
benzene ring by naphthalene increases the thermodynamic hardness of the
macromolecule. It was found that the dependence of the diffusion coeificient

only sliglit'in CCL4and more marked in benzene. This confirmn that the
dependence on the concentration is mainly determined by the thermodynamic

TITLE: Synthesis and investigation of the structure of catalytic
poly-n-butyl methacrylate. II. Optical anisotropy of
molecules of the poly-n-butyl methacrylate stereoisomers
PERIODICAL: Vysokomolokulyarnyye soyedineniya, v- 4, no. 4, 19621 577-582
TEXT: Dynamic double refraction in solutions (benzene) and photoelastic i
effect in films were studied with atactic, syndyotactic and isotactic Btereo-'
isomers of poly-n-butyl methacrylate (FIBMA). The optical measurements made
by the standard method showed that double refraction L n as a function of
the speed gradient is linear for all stereoisomers. Dynamic-optical proper-
ties of solutions of syndyotactic and atactic polymers practically coincide.
The negative:optical anisotropy of these samples proved to be 3even times
higher than that of isotactic PBMk. The photoelastic effect of syndyo- and
atactic polymers was measured at +70 to OOC and the isotactic polymer at +400
to -2500. The photoelastic properties of syndyo- and atactic polymers also
almost agree. In a highly elastic state negative anisotropy was established'
for them. In the temperature range investigated, the anisotropy of isotactic!

samples proved to be positive and, in the highly elastic state of the samplej
two to three times higher than the photoolastic constant It of the two oiherai
Concluciont The data determined point to a similarity of atactic and syndiod&:
tactic microstructures. During transition from atactic to isotactic struc-
ture a reduction of the negative anisotropy of the macromolecule takes placel
which leads to a change of the sign of the photoelastic coefficient. This
strong change of anisotropy may be explained by slight change of the rota-
tional character in the ester side group. High sensitivity of the optical
anisotropy of molecules to their spatial arrangement seems to be character-
istic for polymers of the methacrylate series. It is, therefore, possible
that the determination of the optical anisotropy of macromolecules of similar,
polymeric systems could be used as a sensitive method of investigating theirl'
spatial arrangement. There are 5 figures and I table.

TEXT; Polystyrene of molecular weigh0?2-10 3 was grafted on polymethyl

methacrylate, molecular weight 7-10 . Refractometric examination of the
copolymer composition showed the molar p%rt of polystyrene to be 0.9. Thq
average-weight molecular weight of ;4(0-5.- 0'.6)-10 6 was determined by :~"
light scattering. Analysis of the diffusion curve proved the content of-ili-e-
low-molecular components to be no more than 5-101a.' The optical anisotropy
of the copolymer was determined by flow birefringence in bromoform.

theoretical calculation of the anisotropy of one segment of the principal
methyl methscrylate chain with short graft polystyrene chains, proved that
(a I-a2) is t220-10- 25cm3, when the polystyrene polymerization coefficient
is 40 and when the molar part of polystyrene is 0.9. The experimental
value, which is four -times as high, 16 explained by the fact that the
chain stiffness of the graft copolymer is higher than that of homopolymers.
Conclusiont The optical anisotropy of a branched polymer may differ
considerably from the anisotropy of its components. There are 5 figures

TITLE: Development of a method for evaluating the technological properties of polyvinyl-
chloride resins from their maximum rate of dissolution in cyclohexanone
SOURCE: Plasticheakiye massy*, no. 8, 1964, 24-27
TOPIC TA(3S: polyvinylchloridei, resin, cyclohexanone, tableting, resin mechanical
property, resin evaluation, cyclohexanone solubility, polyvinylchldride solubility
ABSTRACT: In order to develop a new testing technique, the technical properties of poly-
vinylchloride resins were determined and compared with the Idnetica of dissolution o
microsamples in cyclohexanone. The preparation of the sample and the design d the mold I
for tableting the resin are described. A disk 16 mm in diameter was cut out from the
molded tablet and dissolved in 40 ml of freshly distilled cyclohexanone in a glass ves'Bel at
i a temperature of 50 + 0. 1C. The weight of the sample before the experiment was 58-60 mg.!'
At 3 -minute Intervafs-, for 46-60 min., the weight of the sample was determined to 0. 1-0. 2 1
mg. The amount of dissolved polymer (mg) and the rate of dissolution s(mg/min) were then!
plotted against time in integral and differential curves, respectively. The maximum dia-
solution rate depended on the average molecular *eight of the'resin. Two rates appeared

on the kinetic curves: a low and high final rate of dissolution. A polymer having unbranched
molecules and a homogeneous molecular-weight distribution (low degree of polydispersity)
can be dissolved at a high final rate. The low final rate is due to either high branching of
the polymer chains, or high polydispersity. Both factors also Impair the processabi ity o
the resin. The following characteri sties were obtained: a (max. rate) = 1. 13 mg/m- in.,
final rate = 0. 50 mg/min., max.r = 36 min., total = 44 min., v (slowing down of the
dissolution at the end of the reaction) - 0. 064 mg/min.; sfi , m d v are thus the
nal s ax an
most important characteristics. There is a great difference between resins obtained by
latex polymerization and those obtained bysuBpension polymerization. The ffinal, fmax
and v values are high for latex resins; thus they are very processable. This method is a
good control method for making resins, because it simultaneously gives information as to
the expected behavior of the polymers during processing. Orig. art. has: 9 figures, 3

ABSTRACT: To investigate the extent to which the optical properties of the original parent
polymers are preserved in grafted copolymers, the authors incasured tile photoclasticity
of films prepared from 1. three copolymers produced by grafting polystyrene on
polymothylmothacrylate, and 2. two copolymers produced by grafting polystyrene on
poly-n-butylmethacrylate. The copolymers, prepared by ionic catalytic polymerization,
differed in chain length (M=600. 103 and 200 - 103 in the main chain and 2 - 103 and
24 - 103 in the grafted chain) and in the percentage of grafted polystyrene (13, 80, 86 and
88). The films were prepared by vaporization of benzene solutions. A previously described
method was used to examine the behavior of the double refraction of the films in time as a

function of stretching stresses intermittently applied at temperatures ranging from that of
copolymer mechanical softening to that of fluidization. The temperature range of increased
elasticity was found to be narrow, with the temperatures of fluidity and vitrification being
close and the photoelastic properties of the grafted copolymers showing a pattern markedly
different from that of the parent polymers. The double refraction observed in,the grafted
polymer films is understood to result from the superimposition of positive and negative
refractions differing significantly in the relaxation time. "The grafted copolymers were

ABSTRACT: A study was made of the dynamic birefringence of light by a number oi
cellulose ester solutions (nitro cellulose (I), ethyleellulose (lI),and trinitrobenzoate;
cellulose (11.1)),whose molecular chains possess considerable skeletal rigidity, The;,
study was made to determine the effect of the form of cellulose on the above
parameter. The parameter [n), which is the dynamo-optical constant of tile
solution, varied parabolically with variation in the refractive index of the polymer
in the case of I and III, which were characterized by positive and negative intrinsic
anisotropy corresponding to the theoretical. The observed binary refraction for

esters was found to exceed in magnitude by two orders this effect of elastic
polyrr The second property found to be characteristic of these polymers
solution was the independence of the above birefringence on the concentration of
'lie solution in solvents, where the observed effect to a considerable degree is the
effect of the form of the cellulose. It is assumed that the observed dynamo-optic
effects of the ester forms of cellulose are a reflection of the segmented effects of
the microfilm. A bibliography of 13 references is included. Ye. Glazunov.

TITLE: Electrodynamic birefringence of liquids

TOPIC TAGS: double refraction, optical anisotropy, liquid flow

birefringence
ABSTRACT: The combined effect of magnetic and electric fields and hydrodynamic
flow on the optical anisotropy, in particular the birefringence, of liquids was
analytically and experimentally investigated. The analysis shows that the total
effects can be fully explained on the basis of general laws governing the optics of
elliptically polarized light. rormulas determining the total birefringence as the
superposition of two independent anisotropies, the electrooptical and the dynamic-
optical,;were obtained and-adapti!d for-the case of low field strength and velocit
gradients; the formulas also take into account the angle of the polarization
ellipses with respect to the direction of flow, and practically coincide with the
counterpart formulas deduced from the molecular mechanism by, among others, Ikeda
and Mukohata (J. Mol. 1962,.570, and 7, 1963, 442; J. Chem. Phys, 38,
UDC; 535.55(206,2)

1963, 2839). The method was experimentally checked in two types of dynamic-
optimeters described by Tsvetkov and associates (ZhFKh, 24, 1950, 994 and ZhETF,
23, 1952: 690) and Frisman (Vysokomolek. soyed., 3, 1961, 276). In the series of
measurements on low-molecular substances (brormoform, a-methylnaphthalene, a-bromo-.
napthalene, etc.), the orientation of the electrodynamic birefringence proved to be
a linear function of the square of the electric field strength, with the inclination
tangent determined by the ratio - K/A (Kerr and Maxwell constants) for the given
substance. The other group of substances (poly-y-benzyl-L-glutamates in various
solvents), with their high optical anisotropy and strong dipole moment, could be
investigated structurally in a single experiment using the method of electrodynamic
birefringence. Solutions in chloroform of various concentration,,; within the
molecular weight range from 6 X 104 to 34 X 104 showed the same linearity of the
dependence of orientation on the electric field strength, except for the change of
sign at certain field-strength values. Thus, the macroscopic formulas proposed by
the authors describe fully the phenomena of birefringence of liquids independently
of the consideration of the molecular mechanisms such as polarity, dipolar and
anisotropic members in the orientation of molecules in the electric field, direction
of dipole moments in the molecule, etc. Experimental data, extrapolated for an
infinite dilution, can yield information on the structural characteristics of a
given substance. Orig. art. has: 11 formulas, 3 figures, and 2 tables.

Abstract A check was made on the suitability of the method of differential fil-
ters for the production of mondehromatic intensity curves. For the
Kc,4,-radiation of copper, a nickel and cobalt filter were selected. The
latter were made of different thicknesses from Ni2O and Co203, suspended
in wax. In addition, the nickel filbimr was made o? a foil approximately
7 microns thibk. When choosing the filters, the thickness of one of them
was varied uatil both filters gave identical balckening of the film on
both sides of the copper K(I\line. Photography was in a vacuum camera
to avoid scattering of x-rays by the air. Investigation was made of
x-rays scattered by glass-like selenium, 1wepared by pouring molten
selenium on cold allss. The blackening curve was plotted with allowance
for the corrections for absorption and polarization. The blackening

cur,res obtained with differential filters agree witbin the measwr=eat
accuracy with the curves obtained with a monochromatic beani. A cirrve
of the atomic distribution for seleniura was plotted, and exhibited
three clear maxJna in. the interval frcm 0 to 5 A. The first waxbrom
Is narrow and isolatcd frow the renaining ones. This is caused by
the fact that the structure of the g-laso-like selenium is based on the
molecule. The distance between the neareat selenium atoms turned out
to be 2.5 A, which In in good agreentent with the distance betiverun the
atoms of -the molecule of crystalline selenium. In addition, there is
appareutly also a similarity in the structures of the moleculei3 of
glass-like and crysta.111-ne selenium. The use of differential filters
gives a satisfactwy degree of moaochromatization and permits reducing
the exposure time by a factor of 8 .-- 10 compared with monochrcmatiz_ntivn
by a planar cryste,l.
