Modification of Poly(Butylene Terephthalate-co-Butylene Itaconate)Copolyesters
摘要
Abstract
A series of copolyesters-poly (butylene terephthalate-co-butylene itaconate)(PBTI)were synthesized by melt polycondensation from dimethyl itaconate (DI),1,4-butanediol (BD)and dimethyl terephthalate (DMT).On this basis, hydrophilic diol(PEG)was selected as comonomer component to react with DI,DMI and BD via direct melt polycondensation. A series of degradable aliphatic-aromatic copolyesters (PBTIG) with different PEG molecular weight and content were synthesized.Hydrolytic degradation results demonstrated that with the increase of the itaconic acid content,the degradation rate was speeded up,andthe hydrophilic PEG significantly increased the degradation rate of the copolyesters.The hydrolysis experiments showed that after 1 60 h,the residual of the PBTI was 91.35%,while,the residual amount is only 81.20% after adding hydrophilic PEG.The degradation rate was increased by 1 1 7.34% than PBTI.关键词
