全氟酰基过氧化引发剂

Perfluorodiacyl peroxide initiators

综述了全氟酰基过氧化物引发剂的优点、合成方法及其用途。通过全氟酰基过氧化物引发剂引发烯类单体(如丙烯酸、乙烯硅等)可在相应聚合物链上引入氟端基,氟端基聚合物具有极强的表面活性,当水溶液中或聚合物混合物中含有极少量的氟端基聚合物时,即会发生向表面的强烈吸附现象。并简要地介绍了它作为对芳环、芳杂环有效的全氟烷基化试剂及烯烃聚合的引发剂在合成含(全)氟功能化合物领域中的重要作用。

Perfluorodiacyl peroxide initiators＇ merits, its synthetic method, its use and the thermal decomposition mechanism were summarized. Perfluorodiacyl peroxides could produce the fluoroalkyl end - capped polymers of the monomers such as acrylic acid and vinylsilane etc. Generally, fluoroalkyl capped polymers are high surface active. The end- capped polymers were concentrated at tile interface, i. e., the segregation was happened, in the solution or meh of polyblends containing the end - capped and ordinary polymer. And perfluorodiacyl peroxides applications as effective aromatic ring- perfluoroalky - lating agents and initiators of oligomerization was reviewed.
