| titleOfInvention | Cyclic olefin polymer, method for producing same, and optical element |
| abstract | The purpose of the present invention is to provide: a cyclic olefin polymer which has high refractive index, low Abbe number and low birefringence at the same time; a method for producing this cyclic olefin polymer; and an optical element which uses this cyclic olefin polymer. A cyclic olefin polymer according to the present invention is a polymer or a hydride thereof, said polymer containing, at a predetermined ratio, a structural unit derived from a naphthyl group-containing alicyclic compound (A) that is represented by formula (1) (wherein one of R2a to R5a moieties represents a naphthyl group, and the other moieties and R1a moiety are as defined in the description). |
