Synthesis and Characterization of Poly(Butylene Terephthalate-co-Butylene Itaconate)Copolyesters
摘要
Abstract
A series of biodegradable aliphatic/aromatic copolyesters-poly(butylene terephthalate-co-butylene itaconate)(PBTI) were synthesized by melt polycondensation using dimethyl terephthalate (DMT),1,4-butanediol(BD)and dimethyl itaconate (DI)as raw materials.The effects of polymerization time,temperature,as well as aliphatic/aromatic mole ratio on physical and thermal properties of the copolyesters were investigated.The structure of the copolyesters was studied by 1 H-NMR and FT-IR.DSC,TGA and GPC analysis clearly indicated that the molecular weight,glass-transition temperature and melting point were influenced by the ratio between DMT and DI in the final copolyesters.In addition,the effect of mole ratio between DMT and DI on the degradability of the copolyesters was studied.Results showed that the degradability of the copolyesters was gradually improved with the increase of the aliphatic units in the chain.关键词
