PROCESS FOR PRODUCING HYDROGENATED POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a highly transparent hydrogenated polymer including a step of hydrogenating aromatic rings of an aromatic vinyl compound-(meth) acrylate copolymer, the hydrogenated polymer is stably and rapidly produced for a long period of time or repeatedly. SOLUTION: The invention relates to the process for producing the hydrogenated polymer comprising hydrogenation of the copolymer having a ratio, A/B from 0.25 to 4.0 (A is a molar number of constitutional units derived from the (meth)acrylate monomer, and B is a molar number of constitutional units derived from the aromatic vinyl monomer) in a solvent in the presence of a catalyst which is composed of zirconium oxide supporting palladium.
