含噁唑啉环的活性聚苯乙烯制备

The preparation of Reactive PS Containing Oxazoline Ring

本文介绍以2—乙烯基—2—噁唑啉和苯乙烯为原料,用自由基悬浮共聚和本体共聚合成活性聚苯乙烯的方法。用粘度法测定了活性聚苯乙烯的分子量,用红外、定氮的方法对共聚物的组成进行了表征。结果表明,用本文所述自由基悬浮聚合或本体聚合方法都能合成含噁唑啉环的活性聚苯乙烯。在加工条件下,活性聚苯乙烯中的噁唑环能与其他聚合物发生接枝反应,显示出其活性。

Methods for the synthesizing of reactive PS from divinyl—dioxazoline and styrene by means of suspension polymerization and bulk polymerization were introduced in this paper. The molecular weight of the reactive PS was measured by voscosimetry and the composition of the reactive PS was characterized by IR and the determination of nitrogen contents in the reactive PS. The results showed reactive PS containing oxazoline ring could be synthesized by the suspension polymerization and bulk polymerization mentioned in this paper. A graft reaction took place among tee oxazoling in the reactive PS and other polymer on processing condition ,showing reactivity.
