【摘要】 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%).更多还原

【Abstract】 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.更多还原
