测定了甲基丙烯酸三丁基锡醅与甲基丙烯酸甲酯共聚物的~1H-NMR谱。研究了共聚物组成不同,共聚物组成相同但分子量不同,以及实验条件(如pH值和温度)不同对聚合物水解速率的影响。根据电子探针观测,聚合物水解前后,膜表面的有机锡含量和分布基本相同。分别计算了聚合物和共聚物水解的表观活化能。
The? H-NMR spectrum of the tributyltin t-butylmethacrylate copolymer was measured. The effects of different copolymer compositions, same copolymer composition but different molecular weights, and different experimental conditions (such as pH value and temperature) on the hydrolysis rate of the polymer were investigated. According to the electron probe observation, the content and distribution of organotin on the surface of the membrane are basically the same before and after the polymer is hydrolyzed. The apparent activation energy of the hydrolysis of polymers and copolymers were calculated.
