## Abstract Analyses of the isothermal and nonisothermal melt kinetics for syndiotactic polystyrene have been performed with differential scanning calorimetry, and several kinetic analyses have been used to describe the crystallization process. The regime IIβIII transition, at a crystallization tem

## 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 **Summary:** Molecular weight (MW) effects of atactic polystyrene (aPS) on the morphologies and crystallization kinetics of syndiotactic polystyrene (sPS) blends have been investigated, and miscibility was confirmed for all the sPS/aPS blends. Addition of aPS(M) or aPS(L) leads to a sig
Nonisothermal melt and cold crystallization kinetics of poly(aryl ether ketone ether ketone ketone) (PEKEKK) were investigated by differential scanning calorimetry (DSC). The Avrami equation modified by Jeziorny could only describe the primary stage of nonisothermal crystallization kinetics of PEKEK
