线形有机锡聚合物的配位交联对溶液性质的影响

The Effect of Coordination Crosslinks on the Solubilities of Linear Organotin Polymers

摘要: 聚甲基丙烯酸三烷(芳)基锡酯CH_2C(CH_3)COOSnR_3_n的锡原子与羰基氧之间存在着结构单元之间和结构单元内部的配位,可使高分子链间产生配位交联。本文研究这种配位交联对聚合物溶液性质的影响,发现溶剂能促使配位交联键的解离,解离速度与溶荆性质有关,并且提出解离机理和动力学方程。还讨论了锡酯基团中取代基尺寸对聚合物极性和溶解性能的影响。

Abstract: The effect of coordinate bonds on the solution properties of organotin polymers have been studied. The dissociation of coordinate bonds can be accelerated by solvent. The rate of dissociation is dependent on the polarity of solvents. The kinetic eqation o
