PROBLEM TO BE SOLVED: To obtain a hydrogenated cyclic conjugated diene copolymer excellent in impact resistance, heat resistance and transparency, and to provide a resin molded product for optical applications made of the same. SOLUTION: The hydrogenated cyclic conjugated diene copolymer is obtained by hydrogenating a random copolymer having a 1,2-linkage comprised of 80-95 pts. wt. of a cyclic conjugated diene monomer and 5-20 pts. wt. of a linear conjugated diene monomer. The resin molded product for optical applications is made of the same. COPYRIGHT: (C)2005,JPO&NCIPI
