摘      要：Crystallization behavior of poly(ethylene terephthalate-co-ethylene isophthalate)(PEIT) with different isoph-thalate contents (4%, 8% and 12%, designated asPEIT4,PEIT8 and PEIT12 respectively) has been inves-tigated by DSC and density measurement methods. Theresults show that the crystailinity of PEIT decreases withincreasing isophthalate content. However the crystallinity of PEIT8 is much smaller than that of PEIT12 whencooling from melt at a constant *** crystailinity ofPEIT8 cold-drawn filament shows almost the same val-
