聚联烯由于其特殊的结构而使其具有一些独特的应用, 但聚合方法的局限性限制了聚联烯共聚物的研究. 合成了一种偶氮-TEMPO (2,2,6,6-四甲基哌啶氮氧自由基)双官能团引发剂, 通过苯基联烯醚单体的自由基聚合和苯乙烯的NMRP(氮氧调控自由基聚合)活性聚合, 制备了聚苯乙烯-b-聚联烯-b-聚苯乙烯三嵌段共聚物. 通过这种机理转换的策略, 我们可以方便地制备聚联烯与其它类型聚合物的共聚物, 从而拓展聚联烯的应用.

关键词: 聚联烯, 嵌段共聚物, 双官能团引发剂

Polyallene has some particular application due to its unique structure, but study on copolymer containing polyallene was limited because of its polymerization methods. We first prepared Azo-TEMPO (2,2,6,6-tetramethyl-1-piperidine-N-oxyl) bifunctional initiator. Next, PS-b-PPOA-b-PS [Polystyrene-b-poly (phenoxyallene)-b-polystyrene] was prepared by sequential radical polymerization of phenoxyallene (POA) and NMRP (nitroxide-mediated radical polymerization) of styrene. Polyallene-based copolymer was easily prepared by the mechanism transfer strategy, which greatly expands its application.

Key words: polyallene, block copolymer, bifunctional initiator
