Non-isothermal crystallization behaviors in poly(ethylene-co-ethyleneoxyethylene terephthalate)s

摘要

Poly(ethylene terephthalate) (PET) exhibits excellent thermal and mechanical properties,high chemical resistance,and low gas permeability,so that it is widely used in the chemical industry.However,PET still has some undesirable properties to be improved;for example,poor dyeability,pilling,low moisture regain,generation of static charges,poor adhesion to metals,and poor processability due to the high melting temperature.
