摘要: 铂催化硅氢加成的机理、副反应、聚合物性能等均有报道,个别文献用粘度、扭变模量表示反应进行的程度,并没涉及含氢硅氧烷的结构对硅氢加成反应速度的影响.本文合成一系列含氢硅氧烷模型化合物,采用1H NMR测定乙烯基含量的变化,研究反应速度.

Abstract: A series of hydrosiloxanes were preparcd as model compotinds for hydrosilylationstudy of 1,3-divinyl-1,1,3,3-tetramethyl-disiloxane in relation to their vinyl contents.Theresults show that the rate of hydrosilylation depei1ds on the structtire of the hydrosiloxane.
