ABSTRACT:
Polyisocyanates containing dissolved or colloidally dispersed polymers containing rigid moieties are disclosed. Included among the dissolved or colloidally dispersed polymers are polymers ethylenically unsaturated polyaromatic compounds, ethylenically unsaturated benzoic acid derivatives, ethylenically unsaturated steroid derivatives, and rigid aromatic polyurethane and/or polyurea polymers. The dissolved or colloidally dispersed polymers provide substantial reinforcement and physical property improvement to polyurethane or polyurea polymers made from the polyisocyanate solution or dispersion.
