摘要： 本文合成了顺丁烯二酸甲基三丁基锡酯(MTBTM)和顺丁烯二酸乙基三丁基锡酯(ETBTM),并利用该单体分别与VAc和St进行共聚反应,着重从聚合温度、单体浓度、聚合溶剂等条件探讨其共聚规律,发现在一定条件下,MTBTM和VAc共聚,转化率可达到88%。用红外光谱、1H-NMR和元素分析等方法对共聚物结构和组成进行了表征。MTBTM和VAc、MTBTM和St、ETBTM和VAc、ETBTM和St的共聚物均可溶于多种普通有机溶剂中。在常温下,MTBTM与VAc共聚物和ETBTM与VAc共聚物为透明的弹性体,MTBTM与St共聚物和ETBTM与St共聚物为白色脆性固体。

Abstract: The authors have synthesized methyl tributyltin maleate (MTBTM)and ethyl tributyltin maleate (ETBTM). Two monomers were copolymerized with vinyl acetate (VAc) and styrene (St) alternatively.The copolylmerization conditions, such as temperature,concentration of monomers and solvents were examined.The conversion of coplymerization of MTBTM with was was found up to 88%.Copolymers were characterized by IR, 1H-NMR, elementarl analysis and intrinsic viscosity.Copolymers of MTBTM-VAc, ETB-TM-VAc, ETBTM-St and ETBTM-St are soluble in many organic solvents and the first two are transparant elastomers, while the last two are white and brittle solids.
