以1,1'-二乙烯基二茂铁和丙烯酸乙酯为原料,分别用自由基聚合法和阳离子聚合法合成了聚1,1'-二乙烯基二茂铁-丙烯酸乙酯.用XRD,IR,1HNMR,GPC和XPS对由两种不同的方法制得的产物进行表征,研究表明自由基共聚物内的二茂铁单元以桥式结构存在;而阳离子共聚物的二茂铁单元有两种不同结构:一个烯基未参与聚合反应的悬挂结构(38.9%)和两个烯基分别成链的交联结构(61.1%).
Poly( 1,1'-divinylferrocene-co-ethyl acrylate) was synthesized by radical polymerization and cationic polymerization respectively. The copolymers were characterized by XRD, IR, ^1HNMR, GPC and XPS spectra. The results showed that the unit containing ferrocene in the radical copolymer was of three-carbon bridged structure resulting from intramolecular addition. While two sorts of ferrocene units appeared in the cationic copolymer: one had a pendent vinyl group which had not taken part in the polymerization, and the other had a cross-linking structure with two alkenyl groups.
