Abstract
Thermoset polymers are prepared by reacting an ethylenically unsaturated resin monomer and a bicyclic amide acetal with a polyisocyanate in the absence or presence of a vinyl monomer. Reaction rates are suitable for effecting RIM processing. The resultant polymers exhibit improved impact resistance. Further variation in physical properties can be achieved through the use of a diol chain extender for the polyisocyanate.
