Abstract
An oxidated silicon compound will react with a substituted organic compound in the presence of an alkali compound to produce organic alkali metal silicate products which may be used as molding powders, as adhesives, as coating agents and be reacted with polyisocyanates to produce insulating foams.

The process for the production of poly(vinyl organic alkali metal silicate) polymer by the following steps:
- (a) Mixing and reacting an oxidated silicon compound selected from the group consisting of hydrated silica, sodium silicate, potassium silicate, natural oxidated silicon compounds containing free silicic acid radicals and mixtures thereof, and alkali metal compound selected from the group consisting of alkali metal hydroxides selected from the group consisting of sodium hydroxide, potassium hydroxides, alkali metal carbonates selected from the group consisting of sodium carbonate, potassium and mixtures thereof in an aqueous solution and an organic compound which is attached to a substituent which will split off during the reaction is a substituted hydrocarbon which contains a substituent selected from the group consisting of halogen, acid sulfate, nitrate, acid phosphate, bicarbonate, formate, acetate, propionate, laurate, oleate, stearate, and oxalate, acid malonate, acid tartrate, acid citrate and mixtures thereof thereby producing an organic alkali metal compound, then
- (b) mixing and reacting 50 to 100 parts by weight of the organic alkali metal silicate compound, 50 to 100 parts by weight of a vinyl monomer selected from the group consisting of styrene, vinyl acetate, vinyl chloride, vinylidine chloride, acrylic acid monomers, acrylate monomers, acrylonitrile and mixtures thereof;
- and a catalytic amount of a peroxide initiator thereby
- (c) producing a poly (vinyl organic alkali metal silicate) polymer.
