摘要
甲基丙烯酸Ｎ，Ｎ－二甲氨乙酯（ＤＭＡＥＭＡ）与溴正丁烷在丙酮溶剂中进行季铵化反应，制得甲基丙烯酸季铵盐酯（ＭＢＤＭ）；然后以ＡＩＢＮ为引发刑，ＭＢＤＭ与苯乙烯（Ｓｔ）在溶液中进行自由基共聚，制得阳离子共聚物Ｐ（ＭＢＤＭ－Ｓｔ），其结构用红外光诸法鉴定，并经￣１ＨＮＭＲ和元素分析表征，证实有可能根据δ２．８～４．１和δ７．２２处两个共振峰确定共聚物的组成．
Quaternary ammonium salts of dimethyl amino ethyl methacrylate (MBDM) were prepared through the reaction of dimethyl amino ethyl methacrylate(DMAEMA) and nbutyl bromide in the solvent of acetone. Then, using azobisisobutyronitrile(AIBN) as initiator, MBDM and styrene as comonomer free radical solution copolymerization was carried out to obtain cation MBDM-St copolymer. In this paper, the structure and composition of P(MBDM-St) were identified by IR spectrum,￣1H-NMR and elementary analysis.It was proved that its composition could be determined according to two resonance peaks at δ 2. 8～4. 1 and δ 7. 22.
