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.
