    Notes: Abstract A method of obtaining and interpreting thermomechanical curves has been developed to facilitate the study of crosslinking and degradation processes in multicomponent polymer systems. The method is highly sensitive and makes it possible to study on small specimens a variety of structural changes governed by the nature of the polymer, by the macrostructure of the test pieces, by the mixture composition, and by the action of various external factors. It is also shown that the thermomechanical characteristics can conveniently be used as a criterion for evaluating working properties (e.g., heat resistance, etc.).

    Notes: Abstract A demonstration is given of the possibility of using the thermomechanical characteristics (temperature dependence of strain in uniaxial tension) of polymer films in the low-temperature range as a rapid and sensitive method of estimating brittleness temperature. A description of the apparatus is given, together with experimental data on the variation of the brittleness temperature of PVC films as a function of the type and amount of plasticizer and filler, and in the aging process. These results illustrate the possibility of utilizing the method for estimating an important property — brittleness temperature — and studying the structural transformations that affect the temperature threshold of deformability of polymers.
