ABSTRACT:
The instant invention is directed to a novel process for the production of inorganic/organic plastic materials and the resultant products. The process generally comprises reacting an aqueous alkali metal silicate solution with a liquid organic polyisocyanate having a viscosity at 25.degree. C of at least about 400 cP. Preferably, the process is utilized to produce high quality, lightweight foams having excellent physical properties.
