Abstract

The effect of tension and compression on the crystallization rate of cis-1, 4-polybutadiene vulcanizate has been investigated. The crystallization kinetics of deformed specimens were studied by measuring the stress relaxation. A linear relation, common to tension and compression, was observed between the logarithm of the crystallization half-period (log τ1/2) and the true stress in the specimens before the onset of crystallization. The crystallization time of the unstressed specimen can be found from the intersection of the straight line with the log τ1/2 axis. The dependence of log τ1/2 on the degree of deformation is linear only in the region of relatively small strains.
