ABSTRACT:
Silicic acid is reacted with a suitable polyalcohol by using heat and an alkali catalyst to produce a polyalcohol silicate. The polyalcohol silicate is then reacted with a suitable isocyanate to produce a poly(urethane silicate) resin. An activator, such as water, may be mixed with the said resin to cause foaming and/or cross linking of the polymer.
