Abstract
Abstract Polyamide silicate resinous products are produced by reacting halosilicon acids with a polyamine compound and a polycarboxylic acid and/or polycarboxylic anhydride. The polyamide silicate resinous products may be utilized as molding powders, as films, as sheets, as coating agent, as caulking compound, as an adhesive and in production of polyurethane silicate resins and foams.

Claim 9
Dependent Claim
72 words
The process of claim 1 wherein the halosilicon acids are first mixed and reacted with the polyamine to produce polyamino-silicon acid compound, then mixed with the polycarboxylic acid or polycarboxylic acid anhydride, the mixture being heated to a temperature between the melting temperature of the polycarboxylic acid or polycarboxylic acid anhydride and the boiling temperature of the reactants while agitating for 20 to 120 minutes, thereby producing a polyamide silicate resinous product.
Claim 10
Dependent Claim
73 words
