介绍了阻滞阴离子聚合引发剂体系近十年的研究现状,详细讨论了几代阻滞引发体系各自的阻滞机理,以及在阴离子聚合制备苯乙烯共聚物树脂中的应用。简单介绍了BASF公司应用阻滞阴离子聚合制备高抗冲聚苯乙烯的应用现状,指出了阻滞阴离子聚合活性可控的优点使其具有更广泛的发展空间。
This paper reviewed the development of retarded anionic polymerization in the last decade, discussing the several generations of retarded anionic initiating systems of retarded mechanism, as well as in the anionic polymerization of styrene copolymer productions in the application. In addition, the application of retarded anionic polymerization technique for manufacturing high impact polystyrene of Germany BASF Company was also described briefly, the advantages of retarded anionic polymerization of reactivity controlled lead it to a broader space for development.
