丙二醇,丙撑二醇
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。
