【摘要】 <正>本文使用FTIR测定了60℃下在苯溶液中,A(?)为引发剂,甲基丙烯酸三苯基酯,甲基丙烯酸三丁基(?),甲基丙烯酸三乙基(?)分别与甲基丙烯酸特丁酯进行自由基共聚反应的竞(?)率,结果分别为:r1(TPTM)=0.11,r2=3.28;r1(TBTM)=0.2(?),r2=(?);r1(TETM)=0.073,r2=0.069。实验结果表明,烯类有机(?)单体(?)原子上有机基不同,对其共聚反应的行为有较大的影响。另外甲基丙烯酸特丁酯和甲基丙烯酸三乙基锡酯共聚可得交替共聚物。更多还原

【Abstract】 The copolymerization of triphenyltin methaerylate(TPTM),tributyltin metha-crylate (TBTM) and triethyltin methacrylate(TETM) with t-butyl methacrylate (t-BMA) have been carried out in benzene at 60℃,using AIBN as initiator.The monomer reactivity ratios have been determined by FTIR.The results are rl(TPTM) -0.11,r2-3.28;rl(TBTM)=0.28,r2=0.83 and rl(TETM)-0.073,r2=0.069.respectively. It has been observed that copolymerization behavious of three organotin monomers are related to substituents on tin atom.Alternating copolymer of TETM with t-BMA has been obtained.更多还原
