Abstract

Abstract: Non-isothermal crystallization kinetics of polypropylene/polypropylene grafted
2-acrylamido-2-mcthylpropancsulfonic acid(PP-g-AMPS)at different cooling rates was studied using differential scanning calorimctry. Jcziorny and Mo methods were used to analyze the DSC data. It showed that both methods described the crystallization behaviors successfully. AMPS side chains did not change the crystallization behaviors obviously，however，increased the crystallization rate. The crystallization activation energy of grafted PP was increased.

Key words: polypropylene, 2-acrylamido-2-mcthylpropancsulfonic acid, grafting, non-isothermal crystallization
