Organotin monomers containing dibutyltin groups--dibutyltin citraconate (DBTC) as a new monomer and dibutyltin maleate (DBTM)--were synthesized. Free radical copolymerizations of the organotin monomers with styrene (ST) and butyl acrylate (BA) were performed. The overall conversion was kept low (< or = 15% wt/wt) for all studied samples and the copolymers composition was determined from tin analysis using the Gillman and Rosenberg method. The reactivity ratios were calculated from the copolymer composition using the Fineman-Ross (FR) method. The synthesized monomers were characterized by elemental analysis, 1H-, 13C-NMR and FTIR spectroscopy.
合成了含二丁基锡基团的有机锡单体 - 丁基锡富马酸酯（DBTC）作为一种新单体和马来酸二丁基锡（DBTM）。采用自由基聚合法将有机锡单体与苯乙烯（ST）和丙烯酸丁酯（BA）共聚。所有研究样品的总转化率均保持较低（<或= 15%wt/wt），并使用吉尔曼和罗森伯格法（Gillman and Rosenberg method）通过锡分析确定共聚物的组成。使用芬曼-罗斯（Fineman-Ross，FR）法（FR method）从共聚物组成计算反应性比。通过元素分析、1H-NMR 和 FTIR 光谱对合成的单体进行了表征。
