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。 In this paper, the research status of the block polymerization initiator system in recent ten years is introduced. The retardation mechanism of several generations of retardation initiation system is discussed in detail, and the application of anionic polymerization in the preparation of styrene copolymer resin is also discussed. The application status of BASF in preparing high impact polystyrene by retardation anionic polymerization is briefly introduced. It is pointed out that the advantages of controlled activity of retarding anion polymerization make it have a broader space for development.
