.ABSTRACT: The effect of variations in the chemical composition of the monomeric
unit in polyearb,onates (I) (obtained by phougenation of 4,4-dihydroxydiphe I-
~alkanes) upon the class point of the polymer hasbeen investigated. 'The (7,
prepared according to I. P. Losev,:O. V. Smirnova, and Ye. V. Korovina (Vysokomolek.
isoyed.t 5, 1491, 1963), were derived from monomers prepared by condensation of
various aldehydes or ketones.with: 1) phenol; 2)-0- or' m-cresol; 3) halogenated
phenolso The glass point T was determined by means of thermomechanical testing of
individual samples on ;;;aAmetric scales. It was established that: 1) increase in
the length of aliphatic chains orintroduction of methyl groups into the benzene

ABSTI'LICT: The temperature dependence of acetylcellulose (AC) plasticized with triphen-
yl, tricresyl, and trioctyl phosphates was studied. The AC samples had the same aver-
age molecular weight (70,000) and different contents of bound Ck3cou (62.06-26.30%).
The studies were made in the range from -80 to +1600. It is shown that unplasticized
AC of various degreos of saponification is in the vitreous state at all testing temper-
atures. As the content of bound CH3COOH in AC decreases, the modulus of elasticity in-
creases. The values of elastic deformations of plasticized AC sxrples at temperature
below the glass transition temperature of the plaeticizar decrease sharply as com-
~(PL
pared to unplasticized samples. T,,Ihen the Dlasticizer is present in the liquid state in
ihe polymer,,it increases ihe looseness of-the Packing of structural elements and of
the ~lasticl!,DroDerties of AC. The authors hold that the PL studied Plasticize AC by
inclusion in the intorpacket regions,being typical interpacket PL. A. Kh. ITrans-

TITLE: The heat expansion mechanism in oriented 1-incar p2lymers
SOURCE: AN SSSR. Doklady, v. 167, no. 6, 1966, 1321-1324
TOPIC TAGS: linear polymer, heat expansion, polymer physical chemistry
ABSTRACT: Ileat related changes in the length of samples cut from isotropic cellulose
triacetatelfilm~Ain a direction parallel or perpendicular to the axis of orientation, were
analyzed to clarify the shrinking of polymers when heated. The base film was drawn out
from 15 to 50% in relation to the initial length and pro-annealed in a free state (10 min, 230C).
The temperature of the cut samples was raised at 2 deg/min. The results are plotted graph-
ically and indicate that reversible shrinkage is peculiar only to oriented systems, its intensity
relating to the level of orientation. The effect is characteristic for amorphous or crystalline
polymers and occurs in glassy or elastic states. An interpretation of the observed phenomeno
is given in terms of the amplitude of skeletal temperature vibrations. The authors express

their sincere gratitude to L. 0. ZhItkova for providing them with cellulose triacetate film,
and to N. F. Bakeyev, Yu. M. Mallns~iy, and V. V. Guzeyev for useful discussions on the
results of this work. Orig. art. has: 4 figures.

The Lifting of the Basin of a Tank Furnace Without Dismounting of
the Brickwork (Podlyam basseyna vannoy pechi bez razborki kladki).
PERIODICAL.- Stek]Lo i Keramika, 1957, Nr 12, pp. 19-19 (USSR.).
ABSIRACT: tn the glass melting department of the electric lamp-works Lemberg
(Llvov) it was necessary to lift the basin of a glass melting fur-
nace by 86 cm. The gabarite measurements of the basin amounted to
lo x 5,5 x 4 m. An investigation of the furnace showed that the
furnace was in order and that it was not necessary to repair it.
The total weight amounted to 6o tons. The dismounting and recon-
struction of the furnace would have taken 1~ days. In order to save
time and money the authors suggested to lift the furnace as a whole
by means of 4 locomotive-lifting jacks (see figure), Metal plates
were put under the lifting jacks and two lifting binder under the
longitudinal carriers of the basin. Two men worked at each lifting
Jack. During the lifting which took 6 hours the lifting height and
steadiness of lifting was constantly checked. When the furnace was
lifted by lm the 11fting was stopped. During this time the iron
Card 112 concrete columns were pieced on to cement by means of fire-bricks.

24 hours the furnace was let down to the new columns which took
8 hours. Simultaneously with the lifting times an overhaul of the
regenerators, burners, and other parts was carried out. The lifting
of the furnace was carried out within 2 days, and material and wor-
king power UP to 15o,ooo roubles were saved.

ABSTRACT: The author gives an account of the 9th Conference on High-
Molecular Compounds convened by the AN, USSR, the Ministry of
Higher Education of the USSR and the Moskva State University
imeni M.V. Lomonosov. About 1,500 scientists and engineers
participated in the conference, among them delegates from
Communist satellite countries and from Israel. In his open-
ing speech, Academician V.A. Kargin described the development
of research and production in the field of polymers, pointing
out the need for new methods of research and processing in
connection with the utilization of high-molecular compounds
and their products. In six sections of the conference 187
discourses and reports were heard, deeling with the synthesis
of polymers, their chemical properties and modification, mole-
cular structure and solutions, formation and mechanics, aging
and destruction. The conference proved that considerable pro-
gress had been made in scientific research and industrial pro-

ABSTRACT: The author mentions the decisions of the Plenary
Session of the Central Committee in May 1958 on a
stepped-up development of the Soviet chemical in-
dustry and the production of synthetic materials.
Ile outlines the use of polymers in photography,
CD
past and present, mainly with respect to film base
and dope, Upon a general discussion on polymers
and their properties, the author states that since
abowl~ 1933 the bulk of Soviet sub-standard film
was produced on an acetate base. Bu-., as compared
wil:h nitrocellulose films, the acetate-base photo-
material has two principal shorl -ii ng s

acetate with a 6e'.5%-content of combined acetic
acid was not satisfying either, since these films
were of ar. increased brittleness, The int.-oduc-
tion of plasticizers gave the molecule chains more
flexibility, but research is continuing towards a
more perfect film material, Related problems, the
solution of which is being attempted in the USSR
as wl-11 as abroad, include an understanding of the
mechanism of plasticizing of cellulose triacetates
and the products 0f their partial saponification,
the selection of suitable plasticizers, and the
understanding of the dissolving mechanism of the
cellulose triacetates, especially .hose that are
made by the method of heterogeneous acetylation.
The author describes American and West German re-
search and intermediate results in this field, lie
concludes that considerably improved films may
eventually result from the combined efforts of the
researchers.

As additives intended to supply these properties,
authors recommend reducing agents of the aldehyde
type (p-dimethyl-amino benzaldehyde) and substances
of the type of o( -naphthol. The studies of chemi-
cal and, most recently, optical sensitization of
photographic synthetic polymer emulsions, the author
says, deserve mentioning. In the following section
of the article the two main trends in the search of
synthetic polymers, which are intended for color
photoCraphy based on the subtractive color process
are discussed. One of these is t~ie study of polymer
dyes in the usual three-layered color -,hoto materials,
whereas the other is based on the effort to create,
with the aid of synthetic polymors, a new technolo-
