摘要

Abstract

Network polymers in a rubber or a gel often contain non-uniform chain lengths. By means of dynamic Monte Carlo simulations of polymer mixtures with various compositions of two chain lengths

we investigated how the factor of polydispersity influences their strain-induced crystal nucleation. Under a high temperature and a high strain rate

the stretching of both polymers revealed that crystal nucleation is mainly accelerated by the presence of short-chain polymers; nevertheless

both polymers join together in the nucleation process. Further analysis proved that crystal nucleation is initiated from those highly stretched short segments

which are rich on the short-chain polymers.
