摘要：
The synthesis of polydimethylsiloxane-polyalkyleneoxide block copolymers has been carried out in solution by hydrosilylation reaction of preformed alpha,omega -bis(dimethylhydrosilyl) polydimethylsiloxane (HcPDMS) oligomers to allyl end-capped polyalkyleneoxide (PAO), in the presence of Pt catalyst. The products were characterized by IR, H-1-NMR, C-13-NMR spectrometry, and gel permeation chromatography. The thermal stability was determined by thermogravimetric analysis.
