Abstract: U-polymer, a kind of polyarylate was synthesized by interfacial polycondensation method and its structure was characterized by IRand 1H NMRspectra. Amorphous poly(ethylene terephthalate) (APET) was prepared with introduction of U-polymer to improve the thermal and mechanical behavior of PET. The properties of APETwere characterized by DSCand DMA. The results showed that the APETexhibits amorphism, transparency, higher glass transition temperature(Tg) and higher storage modulus than those of PET.

Key words: Amorphous poly(ethylene terephthalate), Upolymer, Interfacial polycondensation, Molten polycondensation
