Fully cured, intact, solid castings of bis(allyl carbonate) resin, e.g., diethylene glycol bis(allyl carbonate), are prepared by polymerizing the resin with between about 0.75 and about 1.50 parts, per hundred parts of resin, of a monoperoxycarbonate, e.g., tertiarybutylperoxy isopropyl carbonate. An adhesion reducing amount, e.g., between about 25 and about 75 parts, per million parts of resin, of a mold release agent is incorporated into the liquid resin monomer to avoid cracking of the casting. Use of a mold release agent is not required when the resin is prepolymerized to about 15-50 percent allylic utilization.
