摘要

1 引言控制高分子结构、合成和制备嵌段、序列共聚物是目前聚合物合成的重要课题.在各种方法中

活性聚合是简单、经济和较通用的方法.作者曾在低于-70℃的Cl_2/TiCl_4/IBVE(异丁基乙烯基醚)/CH_2Cl_2体系中实现了活性阳离子聚合

温度高于-70℃或用其它溶剂则不能得到活性聚合物.本实验目的是研究在IBVE/Cl_2/TiCl_4体系中加入给电子添加剂DOX(1

4-二氧六环)

通过DOX与增长活性链之间的相互作用

使碳阳离子稳定

探索在较高温度下或其它溶剂中的活性聚合的可能性。

Abstract

The role of dioxane in the cationic polymerization system of IBVE/Cl2/TiCl4 is discussed. It is for the first time to achieve the living cationic polymerization of IBVE in the presence of dioxane. UV spectroscopy was used to characterize the role of dioxane on the propagating chain end. The complexing and solvating mechanism were proposed.
