PROCESS FOR PRODUCING OPTICAL MEMBER, PROCESS FOR PRODUCING PLASTIC LENS, GASKET FOR PLASTIC LENS MOLDING, AND JIG FOR MONOMER INJECTION
摘要
<p>A process for producing an optical member which comprises mixing an isocyanate-terminated prepolymer ingredient (A) with an aromatic diamine ingredient (B) and injecting the mixture into a mold immediately after the mixing to obtain a molded object; a process for producing a plastic lens which comprises mixing the ingredient (A) with the ingredient (B), injecting the liquid mixture into a mold immediately after the mixing, and polymerizing it to obtain a molded object; a gasket for plastic lens molding which comprises a cylindrical object; and a mold for plastic lens molding and a jig for monomer injection which each employs this gasket.</p>
