RESIN COMPOSITION, RESIN MOLDED PRODUCT AND OPTICAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a resin composition that is excellent in transparency and has high refractive index and high Abbe number, to provide a resin molded article produced by using the resin composition and to provide an optical member.SOLUTION: The resin composition contains a cycloolefin resin having a weight average molecular weight (Mw) and a ratio of a carbon number and a hydrogen number in a repeating unit having a ring structure, respectively, in a specific range and a ring structure-containing hydrocarbon oligomer produced by radically polymerizing a cycloolefin monomer and having a weight average molecular weight (Mw) in a specific ratio in a weight ratio (the cycloolefin resin:the ring structure-containing hydrocarbon oligomer) in a range of 99:1 to 30:70. The resin molded product produced by using the resin composition and the optical member are provided.SELECTED DRAWING: None
