聚(丁二酸丁二醇酯己内酯)的扩链改性研究
Studies on chain extension modification of PBSCL
摘要
Abstract
In this thesis, a series of biodegradable chain extended copolymers were synthesized by melt polycondensation from succinic acid, 1,4-butanediol, e-caprolactone and TDI. The chemical structure was characterized by Fourier transform infrared spectroscopic (FT-IR) and hydrogen nuclear magnetic resonance 8pectrum('H-NMR).The differential scanning calorimetry(DSC) test showed that the copolymers have good thermal properties, PBSCL had a decrease in melting point with the increasing content of e-caprolactone. Also, the effects of temperature of the extended reaction and feed molar ratio on the inherent viscosity of copolymers were studied. The results of hydrolytic degradation showed that the rate of biodegradation of copolymers was faster in acid solution.关键词
