| Abstract: | High molecular weight poly(butylene succinate)(PBS)was synthesized by trans-esterification polycondensation.The different kinds and content of catalysts,which were used for the PBS synthesis were summarized and compared in this paper.The results showed that 1,4-butanediol titanate exhibited the highest catalytic efficiency in the synthesis of PBS.When the catalyst(molar ratio)was of 0.05%,the color of product was well with high molecular weight and less by-products in the process. |
