ABSTRACT:
UV-transparent forming tools or molds are prepared for molding resins comprising a urethane acrylate, e.g. urethane dimethacrylate oligomer, and an alpha,beta-ethylenically unsaturated monomer, e.g., styrene, cured in the presence of a peroxide initiator. The resins are tough, durable and have a wide range of other desirable properties.
