The Synthesis And Application Research Of Difunctional Modified Polysiloxane

In the thesis, the review has been systematically made in the current situation of research and applications on the domestic and overseas polysiloxane. Meanwile, the prospect of difuctional modified polysiloxane is predicted.By means of hydrosilication and alcohol decomposition and alkaline polymerization, ammo and pinyl modified polysiloxane was prepared with α -pinene, methyl dichlorosilane, octamethyl cyclobutasiloxane and N- β -aminoethyl-γ -aminoprpyl,methyl,dimethoxyl silane etc. Moreover, the research of application effect on wool textile has been made.Amino and polyether modified polysiloxane was synthesized by amoyiation and alkaline polymerization methods. In the amoyiation method, amino and polyether modified polysiloxane was prepared with silicon fluid containing hydrogen, allyl glycidyl ether and unsaturated polyether by hydrosilication and amoyiation. Wheras, it was synthesized with octamethyl cyclobutasiloxane and N- β -aminoethyl- γ -aminoprpyl,methyl,diniethoxyl silane, silicon fluid containing hydrogen and allyl glycidyl ether by hydrosilication and alkaline polymerization in the other method. Futhermore, the research of application effect on terrylene fabric has been made.By double decomposition and alkaline polymerization, amino and stearamoyl modified polysiloxane was prepared with stearamid , γ -chloropropyl,methyl,diethoxylsilane , octamethyl cyclobutasiloxane and N- β -aminoethyl- γ -aminoprpyl,methyl,dimethoxyl silane as raw material. Meantime, the research of application technology and effect on cotton textile has been made.By alkaline polymerization and acylation, amino and ethamoyl modified polysiloxane was synthesized with N- γ -aminoprpyl,methyl,dimethoxyl silane octamethyl cyclobutasiloxane and acetic anhydride as raw material. At the same time, the analysis and research of application effect on acrilan sock have been made.With octamethyl cyclobutasiloxane , N- ^ -aminoethyl- Y -aminoprpyl,methyl,dimethoxyl silane and gluconolatone as raw material, amino and gluconamoyl modified polysilane was prepared by alkalinepolymerization. Moreover, the research of application effect on silk textile has been made.The technological conditions of hydrosilication that the reaction temperature is 85°C, the reaction time is 6 hours, the molar ratio of methyl dichlorosilane and a -pinene is 1:1.1, the molar ratio of silicone containing hydrogen and unsaturated polyether is 1:1.2, and the technological conditions of alkaline polymerization that the reaction temperature is 135-140°C, the reaction time is 6 hours, and the technological conditions of amoylation that the reaction temperature is 60 °C, the reaction time is 4 hours, and the technological conditions of acylation that the reaction temperature is 50 °C, the reaction time is 2 hours, are concluded by experiment.
