TITLE: Spectroscopic study of substituted acryl- and metlui-
cryl amides and their reaction capacity on polymeri-

TEXT: Spectroscopic methods -- combination scattering and absorp-
tion in. the IR- and Ul[-regions -- were used to study the MultiDle
bond conjugation and the intermolecular hydrogen bonds in metu-hyl-
acry-lamide (I), methylmethacrylami-de (II), dimethylmethacryl-
amide (III), and diethylmethacrylamide (IV)..The presence of inter-
molecular hydrogen bonds was established in I and !I, and it was
shown that the hydrogen bonds substantially influence the degree
of conjugation. The reaction capacity of these compounds in t -ie
process of initiated thermal polymerization, which was determined
by G. 14. Chetyrkina, conforms to the degree of conjugation ascer-
ta4ned from 'he spectral combination-scatter-ing intensity and from
.L -L t, U -L

TITLE: Co- operative effects in the annealing and softening of
polyvinyl acetate
PERIODICAL; Vyookomolekulyarnyye soyedineniya, v- 4, no. 6, 1962,
917-921
TEXT: In continuation of an earlier paper (Vysokomolek. soyed., 3, 1739,
1962) concerning the effect of annealing on the softening of noncrystal-
lizing glassy polymers, the same method was used to determine the relaxa-
tion time T and, at 21 and 29-50C, the specific heat,'Cp, of amorphous
polyvinyl aceta"te (PVA). The equation I/T = d ln(H - H.)/dt was
experimentally checked; F, = enthalpy, He = enthalpy of the equilibrium
state. The following was found: T reexp[-a(H He)1,.where e is the
0
value of -e at H - He a = 7-83 cal-g and Te 0expE-bT( C)J, where

temperature), T depends not only on H but also on He. The dependence of
the function Cp (T) on H - 11 e with different times of annealing showed that
CP Blax = oo after 40 days of annealing. Integration of C P(T) (Fig- 5)
showed that a discontinuity of enthalpy occurred at the soften-ing tempera-
ture (400C). The amorphous polymer imitates a phase transition of the
first order. In addition, an irregularity in the range of C p max was
observed when heating PVA annealed for 40 days, which showed a slight
temperature drop (from ~ 44.9 to -44-70C) during J100 see at a heating
rate of 0.23 cal/g-min. These results are interpreted as proof of the
co-operative mobility of the-macromolecules, which is particularly
noticeable near Ts. There are 6 figures and I table. the most important
