Title:
METHOD FOR PRODUCING OPTICAL MATERIAL, POLYMERIZABLE COMPOSITION FOR OPTICAL MATERIAL, OPTICAL MATERIAL PRODUCTION SYSTEM, METHOD FOR PRODUCING OPTICAL MEMBER, FILM FOR PRODUCING OPTICAL MEMBER, MOLD FOR PRODUCING OPTICAL MEMBER, AND CURED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/113955
Kind Code:
A1
Abstract:
This method for producing an optical material uses a total of 100 parts by mass of two or more different monomers for an optical material and 0.010-2.0 parts by mass of a polymerization catalyst as raw materials to produce an optical material. The method includes: a preparation step for preparing a total of 100 parts by mass of two or more different monomers for an optical material and 0.010-2.0 parts by mass of a polymerization catalyst; and a prepolymerization step for mixing a part of the two or more different monomers for an optical material and at least a part of the polymerization catalyst, and polymerizing at least a part of the part of the two or more different monomers for an optical material so as to obtain a prepolymer, thereby obtaining a mixture containing the prepolymer.
