Abstract

Poly(

-xylylene adipamide)/poly(ethylene terephthalate) (MXD6/PET) copolymers are synthesized by melt copolycondensation with 1-5 wt% low molecular weight PET oligomers into the MXD6 oligomers at 260℃. FR-IR and

H NMR analysis results indicate that the interchange reaction has occurred between MXD6 oligomers and PET oligomers. The thermal behavior of copolymers shows that the melting temperature of MXD6/PET copolymers decreases with the increasing of amount of PET oligomers

while the crystallization temperature accordingly increases. And the equilibrium temperature

is evaluated to be 251.8℃ for the copolymers with 5 wt% PET oligomer adding

which is very close to that of neat MXD6. The tensile and impact strength of MXD6/PET copolymers are significantly improved than that of pure MXD6 by mechanical properties test

and the microfibril structure in the impact fracture sample's surface reveals the feature of ductile fracture.
