PURPOSE:A high-refractive index, colorless and transparent optical plastic material suitable as a material for lenses, prisms, spectacle lenses or the like, comprising a (co)polymer of a specified allyl bromophthalate. CONSTITUTION:A radical polymerization initiator is added to a mixture comprising 100-20wt% allyl bromophthalate of the formula [wherein R1 is H or methyl and R2 is (meth)acryloyl or allyloxycarbonyl] and 0-80wt% other monomers (e.g., methyl methacrylate or diallyl phthalate). The obtained polymerizable solution is poured into a desired mold and polymerized by gradually heating to about 100 deg.C to obtain an optical plastic material comprising a three-dimensional crosslinked polymer. |
