Abstract

A method of making a polysilylether (PSE) polymer includes: cooling a solution of diethylamine to 0° C. under argon; adding cold dialkyldichlorosilane to form a first mixture; slowly warming the first mixture to form dialkylbis(diethylamino)silane; diluting the first mixture with hexane then filtering via cannula; evaporating the hexane and excess diethylamine; purifying the dialkylbis(diethylamino)silane under vacuum distillation; adding the dialkylbis(diethylamino)silane to a solution of diol dissolved in tetrahydrofuran to form a second mixture; heating the second mixture to 60° C. while reflux condensing, and cooling and concentrating the second mixture under vacuum to form a resultant mixture containing the polysilylether (PSE) polymer.
