本文叙述了直接用乳酸与顺丁烯二酸酐及1．2—丙二醇合成含乳酸酯链节的不饱和聚酯的方法，以及含乳酸酯链节的不饱和聚酯与普通不饱和聚酯均交联后进行的加速水解对比实验，结果表明含乳酸酯链节的不饱和聚酯水解降解的程度较高，特别是用甲基丙烯酸甲酯交联者。
This article describes the direct use of lactic acid and maleic anhydride and 1,2-propanediol synthetic lactic acid ester link unsaturated polyester method, as well as containing lactic acid ester link unsaturated polyester and ordinary unsaturated poly The results of the accelerated hydrolytic comparison of both esters showed that the degree of hydrolysis and degradation of the unsaturated polyester containing lactate segments was high, especially those crosslinked with methylmethacrylate.
