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.
Key words: syndiotatic polystyrene, poly(butyl acrylate)-atactic polystyrene, isothermal melt cry-stallization, non-isothermal cold crystallization, core-shell latex particles
