The tensile property test shows that the tensile modulus of samples is decreased after degradation in all conditions which is related to the decrease of crystallinity and conform change of trimethylene glycol conformers during degradation .

拉伸试验证明了试样在各条件下降解后拉伸模量降低，这与试样在降解后结晶度降低和 丙 二醇 基团的邻位 交叉构象 增多有关。
