The crystallization kinetics of poly(ethylene terephthalate) was studied using constant cooling rate, isothermal and quenching experiments. A non-isothermal crystallization kinetics equation based on a single mechanism was used to analyze the data. Different mechanisms of crystallization at low, intermediate, and high cooling rates were hypothesized based on deviation of the experimental data from the single mechanism model.
1. INTRODUCTION
Poly(ethylene terephthalate), PET, is a slow crystallizing polymer, which besides its wide industrial success has also become a subject of many research activities. This is because of its high melting point and good ...
