氯丁橡胶和甲基丙烯酸三丁基锡酯自由基接枝共聚的研究

Studies of Free Radical Grafting Copolymerization of Neoprene and Tributyltin Methacrylate

研究了甲基丙烯酸三丁基锡酯与氯丁橡胶的接枝共聚合反应，测定了单体转化率和接枝率，探讨了共聚合反应的条件．采用红外光谱、核磁共振波谱对共聚物进行了结构和性能的表征，还初步进行了防霉实验．

Graft copolymerization of tributyltin methacrylate onto neoprene wascarried out in benzene using benzoylperoxide as an initiator. The Neoprene-g-poly (tributyltin methacrylate)was isolated from the copolytnerization products by extracting with anhydrous alcohol.Percentage of grafting and grafting effeciency were calculated under different experimental condition.The copolymer was characterized by FT-IR and 1H-NMR. The results showed the occurrence of grafting.
