摘要
通过分子设计合成可溶性聚酰亚胺的方法主要有以下四种:一是在聚合物主链中引入柔性结构单元;二是引入大的侧基或侧链;三是引入扭曲的非共平面结构;四是通过共聚破坏分子链的对称性和重复规整性.
There are mainly four kinds of methods to synthesize the soluble polyamides by molecule designs, i.e. through introducing flexible structure units into the main chains of polymer introducing big lateral bases or lateral chains, introducing the twisted structure, which is not on the same plane, and destroying the symmetry and repeated regularity of the molecule chains by means of co - condensation.
