由高分子反应统计理论,结合~1H-NMR及(13)C-NMR方法,分析了T902抗泡剂的序列结构,获得了该三元无规共聚物分子的链段分布函数。系统研究了分子结构对消泡性能的影响,指出了改善抗泡剂配伍性能的正确途径。
The sequence structure of T902 anti-foaming agent was analyzed by statistical theory of polymer reaction combined with ~ 1H-NMR and (13) C-NMR methods, and the segment distribution function of the ternary random copolymer was obtained. The influence of molecular structure on the defoaming performance was systematically studied, and the correct way to improve compatibility of defoaming agent was pointed out.
