ABSTRACT:
The instant invention is directed to a process for the production of inorganic-organic resins, by reaction of an organic polyisocyanate with aqueous basic solutions having an inorganic solid content of from 20 to 80% by weight in the presence of catalysts and optionally other additives, characterized in that the organic polyisocyanate and the aqueous basic solution are used in a proportion by weight of between 80:20 and 10:90 parts by weight and that organic ammonium compounds are used as catalysts.
