摘要/Abstract

摘要： 本文报道了合成烯丙基端基采氧乙烯大分子单体的两种方法(引发法和封端法)。合成产物具有预期的结构。获得的大分子单体与小分子丙烯酰胺共聚,可得到不同组成的共聚物。考察了大分子单体合成条件和端基重排因素,获得了这种大分子单体制备的适宜条件。

Abstract: Polyethylene oxide(PEO) macromers with allyl-cnd group were synthesized by two different methods (initiating and deactivating). The products obtained were, by means of several techniques, including ¹H-NMR, IR,VPO, GPC and the double-bond titration, characterized accurately, and the results show that such kinds of product possess expected structure. The macromers were copolymerized with smalt molacular acrylamide, and a series of copolymers with different composition can be obtained by adjusting copolymerization condition. Moreover, some evidence concerning allyl-groups rearrangement in synthesis of the macromers has been observed and suitable condition for laboratorial preperation of macromers has been proposed.
