Patent abstract
In the production of a nuclear-hydrogenated polymer, the hydrogenation of an aromatic vinyl compound—(meth)acrylate copolymer is conducted in a mixed solvent comprising an ester compound and an alcohol compound in the presence of a catalyst. By this method, a highly transparent nuclear-hydrogenated polymer is produced safely, stably and quickly, even when the degree of nuclear-hydrogenation is low.
