Abstract
Polyurethane foams based on reactive polyols and polyisocyanates containing a filler are modified with an organofunctional silane containing a hydrolyzable group and an ethylenically unsaturated linkage. The polyurethane foams have improved physical properties including improved stability, compression set, tear resistance, elongation, and tensile strength.
