PROBLEM TO BE SOLVED: To provide a method for producing a hydrogenated polymer having a high transparency in a long term, repeatedly, stably and rapidly, comprising a step of hydrogenating an aromatic ring in an aromatic vinyl compound- (meth) acrylate copolymer. SOLUTION: A fragrance in which A / B (A is the number of moles of a structural unit derived from a (meth) acrylate monomer, and B is the number of moles of a structural unit derived from an aromatic vinyl monomer) is 0.25 to 4.0. The group vinyl compound- (meth) acrylate copolymer is hydrogenated in a solvent in the presence of a catalyst in which palladium is supported on zirconium oxide. [Selection figure] None |
