PROCESS FOR THE PREPARATION OF SUBSTITUTES FOR OPTICAL GLASSES AND POLYMERIZABLE LIQUID COMPOSITION SUITABLE TO THAT PURPOSE

摘要

Substitutes for optical glasses are obtained by submitting to polymerization, in the presence of a free-radical initiator and in bulk, a polymerizable liquid composition containing: a monomer of diethyleneglycol bis(allylcarbonate); oligomers of diethyleneglycol bis(alllycarbonate); a monomer of tris(hydroxyethyl)isocyanurate tris(allylcarbonate); and at least one free-radical initiator.
