Description

The creep characteristics of polyacetals, copolymers and homopolymers with high/low molecular weights were investigated under various loads at 80 degrees C. From the slopes of load vs. log (rupture time) lines, the activation volume, υc, derived from Zhurkov equation was estimated. It was found the value of υc becomes larger with higher molecular weight and that the υc of copolymer is larger than that of homopolymer. From SEM observation and the comparison with υc and the activation volume, υy, of tensile yielding process based on Eyring's equation, we concluded that the creep behavior of the polyacetal should result from the dominant ductile rupture.
