    摘要： A safe and stable production method of a hydrogenated polymer having high transparency, which is a production method of a hydrogenated polymer by hydrogenating aromatic rings of an aromatic vinyl compound-(meth)acrylate copolymer, in which (1) a solvent solution of the copolymer is added to a reactor, which has a solvent and a supported palladium catalyst charged therein, under a hydrogen atmosphere at a rate of from 0.01 to 15 g/hour in terms of the copolymer per unit mass (g) of the supported palladium catalyst, thereby performing hydrogenation reaction, and then such an operation is performed repeatedly that (2) a hydrogenated polymer is obtained from 30 to 90% by mass of the resulting reaction mixed solution, and a fresh solvent solution of the copolymer is added to the reactor, in which the residual reaction mixed solution is left, or to which the residual reaction mixed solution is returned, at a rate of from 0.01 to 15 g/hour in terms of the copolymer per unit mass (g) of the supported palladium catalyst, thereby performing hydrogenation reaction.

    摘要： A process for producing a hydrogenated polymer, which includes a step of hydrogenating aromatic rings of an aromatic vinyl compound—(meth)acrylate copolymer. In the process, the copolymer having a ratio, A/B, of 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) is hydrogenated in a solvent in the presence of a catalyst which is composed of zirconium oxide supporting palladium. By the process, a highly transparent, hydrogenated polymer is stably and rapidly produced for a long period of time or repeatedly.
