摘要
本文使用FTIR法测定了60℃下在苯溶液中,AIBN为引发剂,甲基丙烯酸三苯基锡酯和甲基丙烯酸三乙基锡酯分别与甲基丙烯酸特丁酯进行自由基共聚反应的竞聚率,结果分别为: r_1(TPTM)=0.11,r_2(tBMA)=3.28;r_1(TETM)=0.073,r_2(tBMA)=0.069。实验结果表明,不饱和有机锡酯单体中锡原子上有机取代基团的不同,对其共聚反应的行为有较大的影响。
The copolymerization reactions of triphenyltin methacrylate (TPTM) and triethyltin methacrylate (TETM) with ter-butyl methacrylate (tBMA) have been carried out in benzene at 60℃, using AIBN as initiator. The monomer reactivity ratios have been determined by FT-IR. The results are r1(TPTM)=0.11, r2(tBMA)=3.28 and r1(TETM)=0.069, r2(tBMA) = 0.073, respectively. It has been observed that copolymerization behaviors of the two organotin monomers are related to the substituents on tin atom. Alternating copolymer of TETM with tBMA has been obtained.
