Abstract
Disclosed are polymer blends of bis(allyl carbonate) polymers with polymers of olefinically unsaturated monomers, and the precursor blends of bis(allyl carbonate) monomers with polymers of olefinically unsaturated monomers, and fabricable resins prepared therefrom. Also disclosed is a method of fabricating, e.g., molding, injection molding, extruding, and the like, the fabricable resins. The bis(allyl carbonate) polymer blend is taken to a fabricable state, i.e., a fusible pseudoplastic that does not lose liquid on fabrication, either by admixture or admixture and reaction. The fabricable resin is then fabricated, e.g., extruded, molded, or the like, and then polymerized to a hard polymer. Also disclosed are blends of bis(allyl carbonates), monomeric and polymeric, with polymers having olefinic unsaturation.
