Abstract

A new kind of copolymethyl-epoxysilsesquioxane (CPMES) was synthesized for the first time by hydrosilation reaction of allyl glycidyl ether (AGE) with the ladder-like polymethylhydrosilsesquioxane (Me-H-T) in the presence of dicyclopentadienylplatinum dichloride (Cp₂PtCl₂) as catalyst. The graft polymer was characterized by infrared spectroscopy (IR), ¹H-NMR, ²⁹Si-NMR, X-ray diffraction (XRD), gel-permeation chromatography (GPC), vapour pressure osmometry (VPO), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicate that CPMES possesses good solubility in organic solvents, and a greatly improved thermostability compared with polymethyl-epoxysiloxane with a single backbone.
