Deformation and Strength Properties of 1, 2-Polybutadiene in Uniaxial Extension

Abstract
It has been shown that the deformation-strength properties of 1,2-polybutadiene are determined at temperatures above the glass-transition temperature by its transition from the fluid state to the forced high-elastic and glassy states with increasing rate of deformation and stress. Here the determining role in the fracture of 1,2-polybutadiene is played by the high-elastic strain stored in it, and the regularities of its fracture are similar to those for rubbers.
