Abstract: A two part composition comprising a Part A and a Part B, wherein Part A comprises an oligomer having both isocyanate and acrylate moieties, and an organic peroxide capable of generating free radicals upon decomposition; and Part B comprises a polyol, and a catalyst that can decompose the organic peroxide. In one form, the two part composition of a Part A and a Part B are in admixture. By combining Part A and Part B the isocyanate moieties react with the polyol to produce a combination of a urethane acrylate oligomer, organic peroxide and the catalyst. Then in either order, the combination is exposed to sufficient actinic radiation to polymerize at least a portion of the urethane acrylate oligomer; and the catalyst decomposes the organic peroxide thus generating free radicals, which free radicals polymerize at least a portion of the urethane acrylate oligomer.

Abstract: A non-aqueous, solvent-free formulation for producing clear, transparent, heat-resistant elements, suitable for use as lenses in optoelectronic devices, consists essentially of an acidic, nonpolymerizing acrylic resin; THFA, DMA, HEMA, HBA, or an equivalent polymerizable diluent in which the acrylic resin is dissolved; and a free-radical photoinitiator.
