含环戊二烯络铁基团苯乙烯聚合物的合成和表征

Characterization and Preparation of Styrene Polymers Containing Cationic Cyclopentadienyliron Moieties

介绍了含环戊二烯络铁基团苯乙烯聚合物的合成,并用核磁共振仪、红外光谱仪、差热分析仪对该类聚合物的结构、性质进行了研究和表征。实验表明:在丙酮溶剂中,以偶氮二异丁腈为引发剂,含环戊二烯络铁基团苯乙烯在（60±5）℃进行均聚或与甲基苯乙烯共聚收率高。用凝胶色谱仪分析,聚合物分子量较大,分子量分布范围（PDI）小于3.0。

A novel approach to the synthesis of styrene polymers containing cationic cyclopentadienyliron moieties was accomplished, and the characterization was also studied by 1H NMR,FT-IR,TG. In the solution of acetone, styrene containing cationic cyclopentadienyliron moieties can be homopolymerized and/or copolymerized with 4-methylstyrene in high yield in the presence of 2,2'-azobis(2-methylpropionitrile)at (60±5)℃.GPC determination showed that the polymers have high molecular weight and narrow molecular weight distribution.
