ABSTRACT:
A dry granular alkali metal silicate is chemically reacted with a concentrated mineral acid or an acid hydrogen containing salt to produce a white granular silicic acid compound which will react chemically with a poly(vinyl acetate) polymer by heating the mixture with an alkali catalyst to produce a mixture of poly(vinyl silicate) resin, poly(vinyl alcohol silicate) resin, poly(vinyl acetate silicate) resin and poly(vinyl alcohol) polymer.
