摘要：

Differential scanning calorimeter (DSC) has been used to study nonisothermal crystallization kinetics of nucleation and growth. These studies were done by extending the Ozawa equation for crystallization obtained by cooling poly(ethylene terephthalate) (PET) homopolymer and its blends with polystyrene and nylon 6 at variable rates. PET crystallization proceeds by random nucleation with two-directional diffusion-controlled growth. The apparent activation energy and nucleation facilitation are greater in blends.
