The strain and fracture of polybutylmethacrylate have been studied on uniaxial stretching in alcohols (from ethyl to amyl) and water at temperatures above and below T g . Depending on the duration of the stay of the polymer in an active liquid medium

The strain and strength behaviour of a block copolymer has been studied for various regimes of uniaxial strain at temperatures below the glass transition temperature over a wide range of deformation rates, stresses and deformations. It was shown that

The deformation-strength and viscosity properties of a linear polybutadiene have been investigated under uniaxial stretching in low molecular weight alcohols (from ethyl to amyl alcohol), methyl ethyl ketone and water with equilibrium and nonequilibr

It was found that 10% PVA solutions have a completely different behaviour in water and DMSO under the effect of Li, Mg and La perchlorates. These salts cause a sudden increase in the viscosity of PVA solutions in DMSO over a period of time until the

Polybutadiene of narrow molecular weight distribution, filled with acetylenne carbon black of high activity, was investigated under conditions of uniaxial elongation. The behaviour of the composite resembled that of plastic dispersed systems. The def
