日本东京大学S.Inoue(井上)及其研究小组近十余年用四苯基卟啉铝化物,特别是四苯基卟啉氯化铝(TPPAlCl)和四苯基卟啉烷氧基铝(TPPAlOR)作催化剂对环氧化物、内酯等开环聚合进行了一系列研究,表明用此型催化剂得到的聚合体分子量分布窄(1.05—1.20),能进行嵌段共聚合,并能将CO_2、酸酐等共聚到聚醚或聚酯链中。 S. Inoue (Inoue), University of Tokyo, Japan, and his team have spent more than ten years using tetraphenylporphyrin aluminides, in particular, tetraphenylporphyrin aluminum chloride (TPPAlCl) and tetraphenylporphyrin aluminum alkoxide TPPAlOR) as a catalyst for ring-opening polymerization of epoxides, lactones, etc. A series of studies have shown that the polymer obtained with this catalyst narrow molecular weight distribution (1.05-1.20), can block copolymerization, and CO_2 , Anhydrides and the like into polyether or polyester chains.
