Phthalimidine related polyester, 3,3-bis(4-hydroxyphenyl)-2-phenylphthalimidine-terephthaloyl chloride polyester (p-polyester), was synthesized and polycarbonate-p-polyester block copolymer (PC-co-polyester) was obtained by interfacial polymerization of p-polyester oligomer and general polycarbonate oligomer. Successful synthesis of PC-co-polyester was confirmed by employing 1H nuclear magnetic resonance and gel permeation chromatography. The properties of PC-co-polyester and the blend with general polycarbonate or p-polyester were investigated and the enhancement of heat resistance was prominent without loss of transparency. |
