| 摘 要： | 本文把单个分子链的横截面积与聚合物的玻璃化转变温度联系起来,发现对于所讨论的聚合物,考虑了分子链间的相互作用以后,上面二者之间有一一对应的关系。认为单个分子链的横截面积与聚合物分子链柔顺性有关。同时采用文献17]的方法,得到了1,2-聚丁二烯的分子链的内旋转异构化能,比较所得结果,证实了上面的看法。

| Abstract: | A relationship between the glass transition temperature of a polymer and the cross-sectional area of a single molecular chain is established by taking the intermolecular action into account. It was considered that cross-sectional area of a single chain determines the flexibility of macromolecular chain and this was confirmed from the energy of rotational iso-merization of 1,2-polybltadiene. |
