摘要

以甲基丙烯酸二甲氨基乙酯(DMAEMA)为单体、二硫代苯甲酸异丙苯酯(CDB)为链转移剂、偶氮二异丁腈(AIBN)为引发剂，利用RAFT聚合法合成了聚甲基丙烯酸二甲氨基乙酯(PDMAEMA)。以所得PDMAEMA为大分子链转移剂，丙烯酰胺基偶氮苯(AAAB)为单体，AIBN为引发剂，采用RAFT聚合法合成r PDMAEMA-

-PAAAB共聚物，并考察了 AAAB的RAFT聚合反应动力学，利用FT-IR、

H-NMR、GPC和TG对聚合物的结构和热性能进行了表征。结果表明，PDMAEMA的分子量随聚合反应时间的增加而增加，且分子量分布较窄；PDMAEMA-

-PAAAB嵌段共聚物的分子量随着AAAB单体转化率的升高而线性增加，且分子量分布较窄(PD

1. 3)，聚合反应动力学曲线呈良好的线性关系，且具有较好的热稳定性。

Abstract

Poly[2-(

-dimethylamino)ethyl methacrylate] (PDMAEMA) was synthesized by RAFT polymerization of 2-(

-dimethylamino)ethyl methacrylate (DMAEMA)

using cumyl dithiobenzoate (CDB) as a chain transfer agent and 2

2'-azobisisobutyronitrile (AIBN) as initiator. The resulting PDMAEMA as a macromolecular chain transfer agent and AIBN as a initiator

poly[2-(

-dimethylamino) ethylmethacrylate]-

-poly(acrylamido-azobenzene)](PDMAEMA-

- PAAAB) was prepared by RAFT polymerization of acrylamido-azobenzene (AAAB)

and the Kinetics of the polymerization of AAAB was investigated. The resulting PDMAEMA and PDMAEMA-

-PAAAB were characterized by FT-IR

H- NMR

GPC and TG. The results showed that the molecular weight of PDMAEMA increases with polymerization time

and the molecular weight distribution was narrower; the molecular weight of PDMAEMA-

-PAAAB increases linearly with the increase of the conversion of AAAB

the molecular weight distribution was less than 1.3

and the kinetic curve of the polymerization of AAAB exhibits a good linear relationship

and has good thermal stability.
