Nonisothermal Crystallization Kinetics of Syndiotactic Polystyrene

摘要

Crystallization kinetics of syndiotactic polystyrene were investigated by nonisothermal DSC analysis . Dual-stages crystallization mechanism have bene analyzed and proved by several crystallization kinetics models, such as modified Avrami equation and nakamura equation etc. alpha or beta crystalline forms would be got at quick or slow cooling rate from the melting behavior, respectively. Crystallization kinetics parameters for both forms were obtained and the results could explained the experimental data successfully.
