sPS/PBA-aPS的等温熔体结晶及非等温冷结晶动力学研究
Kinetic Study of Isothermal Melt and Non-isothermal Cold Crystallization of sPS/PBA-aPS Blends
摘要
Abstract
This paper reported a kinetic study on crystallization behavior of blends of syndiotactic polystyrene with poly(butyl acrylate)-atactic polystyrene (sPS/PBA-aPS) core-shell latex particles by differential scanning calorimetry (DSC).Isothermal melt and non-isothermal cold crystallization process of sPS/PBA-aPS blends were analyzed by Avrami'and Mo'equations,respectively.The results indicated that the crystallization time of sPS/PBA-aPS blends increased with an increase of isothermal crystallization temperature,but there was a decrease in crystallization rate.As the heating rate increased,there was hysteresis for the crystallization of sPS phase,and the crystallization peak temperature shifted to a high temperature.关键词
