| 摘 要： | 本文对某些不饱和聚酯应用ＮＭＲ分析、研究确认，不饱和聚酯顺－反异构转化不是在 Ｈ＋催化作用下进行，而是在反应温度下聚酯分子链中顺式双键瞬间发生断裂成单键，实现了顺－ 反异构转化．其异构化程度与聚酯分子链节结构有关，与分子量大小无关．

| Abstract: | Some of the related model compounds were prepared, and then were analyzed and investigated by means of NMR. The results showed that the conversion of the cis-trans isomerization did not bring about in the presence of H+. Cis-double bond in the polyester molecules instaneously broke up into monobond at the reaction temperature and promoted the conversion of the cis-trans isomerization. The extent of isomerization is related to chain element construction, but not dependant on molecular weight. |
