摘要：
Direct condensation of equimolar quantities of dicarboxylic acid and diol without generating any environmental waste is the most ideal method for polyester synthesis. The need for Poly Butylene Succinate (PBS) is going to increase tremendously in the near future because of its biocompatibility. We feel that it is still challenging to seek excellent catalysts for aliphatic polyester synthesis under mild condition like short time. We report here a rapid method for aliphatic polyester synthesis by direct condensation of equimolar quantities of dicarboxylic acid and diol with commercially available and cheap, SnCl2H2O in combination with p-Toluene sulfonic acid monohydrate as catalyst.
