对α-羧基，ω-氨基异双官能聚苯乙烯进行分子内环化，得到主链上含有酰胺基团的环状聚苯乙烯。用氢化铝锂还原酰胺部分，得到大环胺。大环胺与端羧基聚苯乙烯和谷氨酸反应，分别得到蝌蚪形和八字形聚苯乙烯。通过NMR、IR和GPC分析对这些大分子结构进行了表征。
The intramolecular cyclization of alpha-carboxyl, omega-amino heterodifunctional polystyrene was carried out to obtain cyclic polystyrene having an amide moiety in the main chain. The amide moiety was reduced with lithium aluminum hydride to give macrocyclic amine. The reactions of the macrocyclic amine with carboxylic-terminated polystyrene and glutaric acid gave tadpole- and eight-shaped polystyrenes, respectively. These macromolecular architectures were characterized by NMR, IR, and GPC analysis.
