Abstract

Isothermal crystallization kinetics of syndiotactic polystyrene (sPS) is reported in this work with Avrami analytical method. It was found that the spherulite growth rate and overall crystallization rate depend on the crystallization temperatures, average molecular weight (over(M, ̄)W) and polydispersity index (PDI). The experimental results for the melt and cold crystallization processes of sPS revealed that the PDI and over(M, ̄)W exhibit pivotal effects on the crystallization rate, which increases with the decrease of over(M, ̄)W and PDI.
