Title:
METHOD FOR PRODUCING OPTICAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/199875
Kind Code:
A1
Abstract:
Provided is a method for producing an optical material by hydrogenating an aromatic ring of an aromatic vinyl compound polymer (nuclear hydrogenation) to obtain an optical material having adequate heat resistance at a high nuclear hydrogenation rate. More specifically, provided is a method for producing an optical material by hydrogenating an aromatic ring of an aromatic vinyl compound polymer (nuclear hydrogenation), wherein the method is characterized by use of a mixed solvent containing at least one first solvent and at least one second solvent.
