摘要

采用自制的CH

Br为内核的1~3代树枝形聚苄醚为引发剂

以溴化亚铜为催化剂、2

联吡啶为配体、苯乙烯为单体

由原子转移自由基聚合(ATRP)制备得到树枝形聚苄醚-聚苯乙烯嵌段聚合物。对树枝形聚苄醚引发剂的C、H含量进行了元素分析

并对合成的树枝-线形聚合物进行了红外和核磁结构表征。研究结果表明

本文合成的1~3代树枝形聚苄醚引发剂的基本组成与理论组成基本一致

采用这种树枝形聚苄醚为引发剂可以得到确定结构的树枝-线形聚合物

但聚合物末端的-Br官能团在聚合条件下部分发生脱除。

Abstract

Dendritic-linear polyether block polystyrene was synthesized via atom transfer radical polymerization(ATRP)that the dendritic polyether having the core of —CH

copper(I) bromide and 2

2'-biphenyl as the initiator

catalyst and ligand respectively. Element Analysis instrument was used to analysis the content of carbon and hydrogen belonged to the dendritic polyether initiators. IR Spectra and HNMR were chosen to characterize the structure of the dendritic-linear polymers. The results show that the component of the dendritic polyether form the first to the third generations are according with the perfect component; the dendritic-linear polymer initiated by the dendritic polyether have the clear structure

but the bromide at the end of polymer chains may be removed under the polymerized conditions.
