Abstract
Abstract A stable organic polymer-polyol-alkali metal silicate emulsion is produced by mixing an aqueous solution of an alkali metal silicate or alkali metal metasilicate pentahydrate, a liquid polyol, an organic polymer in a fluid state, and a small amount of an acid while heating the mixture to 40° C. to 100° C. and agitating until the mixture emulsifies. The emulsion may be used to produce organic polymer-polyurethane silicate foams and resinous product.
