Process for the production of polyisocyanate silicate plastics utilizing an alkali metal cellulose silicate condensation product

摘要

This invention relates to a process for preparing polyisocyanate silicate plastics by reaction of an alkali metal cellulose silicate condensation product with a compound having at least two isocyanate groups to produce a polyisocyanate silicate prepolymer. The prepolymer is then reacted with an organic compound to produce a polyisocyanate silicate plastic.
