TEXT: The article under .7eview shows that it is possible to elongate
polymers below the temperature of vitrification continuously (without
constrictions) and to study the stress-strain curves quantitatively. Sam-
ples with a cross section of up to 1 mm2 were subjected to tensile tests
in the temperature range +20--L- +1600C. The authors studied polyvinyl-
acetate (PVA) and polymethylmethacrylate (POIA). The changes in the
length and cross section of the samples were examined visually and
photographically- Analyses of numerous experiments have shown that stress-
strain curves usually show peaks in their initial sections if tho sample
doo not tear up to an elongation of - 10 per cent. Contractions were not
ob@ rved in every case (Fig. 1). It may be assumed that the density of
