摘要
The high activ penta-coordinated silicon potassium compound was prepared by the reaction of amorphous silica with the ethylene glycol,catalyzed by the potassium hydroxide,and the ethyl tetra-coordinated silicon compound was synthesized by the reaction of this penta-coordinate silicon potassium compound with allyl chloride.Then the copolymer was prepared by the reactwn of this ethyl tetra-coordinated silicon with the methyl-acrylic acid β-hydroxyl ethyl ester,and its structure and thermal property were characterized by IR,TG,DSC et al.IR indicated the reaction has finished because of no absorption near 1630cm-1.TG indicated the decomposing temperature of copolymer is 300 ℃.DSC indicated the glass transition temperature is 63.1℃.The copolymer was not soluble in any solvent and had no melt-point.All analysis proved the copolymer exists some extent linkage.

Then the copolymer was prepared by the reactwn of this ethyl tetra - coordinated silicon with the methyl - acrylic acid β - hydroxyl ethyl ester, and its structure and thermal property were characterized by IR,TG,DSC et al. IR indicated the reaction has finished because of no absorption near 1630cm^-1. TG indicated the decomposing temperature of copolymer is 300 ℃. DSC indicated the glass transition temperature is 63.1 ℃. The copolymer was not soluble in any solvent and had no melt - point. All analysis proved the copolymer exists some extent linkage.
