摘要
对四氢呋喃（THF）聚合制备四氢呋喃均聚醚（PTMEG）传统的均相催化体系及新开发的非均相催化体系分别进行了综述。重点介绍了80年代中期以来开发的杂多酸类（HPA）新型催化体系在制备PTMEG方面的优点。
The conventional homogenous catalytic Processes and new routines of heterogenous catalytic process for manufacturing polytetramthylene ether glycol (PTMEG) through cationic polymerization of tetrahydrofuran are reviewed. The advanages of new hetempolyacids (HPA) catalytic systems developed since mid.80's are discussed emphatically.
