^(29)Si NMR测定含氢硅油中Si—H键含量

Determination of Si—H Contents in Polydimethylmethylhy-drosiloxanes by ^(29)Si NMR

聚二甲基甲基氢化硅氧烷(简称含氢硅油)是一类反应性有机硅聚合物。这类聚合物中含有的si—H键十分活泼,其化学性质在有机硅工业中十分有用,如合成不同类型的硅油、有机硅树脂、硅橡胶、改性有机硅表面活性剂等。

The Si-H contents in the polydimethyimethylhydrosiloxanes were determined by 29Si NMR. When Si-H contents range from 0.1- 1. 29, the results of determination correspond to those determined by chemical method.
