Abstract
U-polymer, a kind of polyarylate was synthesized by interfacial polycondens ation method and its structure was characterized by IR and H-1 NMR spectra. Amorphous poly(ethylene terephthalate) (APET) was prepared with introducti on of U-polymer to improve the thermal and mechanical behavior of PET. The properties of APET were characterized by DSC and DMA. The results showed th at the APET exhibits amorphism, transparency, higher glass transition tempe rature (T-g) and higher storage modulus than those of PET.
