## Abstract The kinetics of the isothermal and nonisothermal cold crystallization of syndiotactic polystyrene (sβPS) were characterized with differential scanning calorimetry. A JohnsonβMehlβAvrami analysis of the isothermal experiments indicated that the cold crystallization of sβPS at a constant

## Abstract In this work, a two phase crystallization model based on the extension of the Kolmogoroff approach was proposed and verified by comparison with experimental isothermal and nonisothermal crystallization data of Syndiotactic Polystyrene (sPS) in a very wide range of cooling rates, up to 6
Polymerization pressure has a direct effect on the synthesis of syndiotactic polystyrene (s-PS) with metallocene as a catalyst. The polymerization rate, yield rate, and average molecular weight show a linear relationship with pressure, that is, they all increase with increased polymerization pressur
