Disclosed are: a cyclic olefin ring-opening polymer which has high refractive index, high Abbe number and solubility in a solvent and is useful for applications as optical materials; a hydride of the cyclic olefin ring-opening polymer; and a composition of the hydride, in which a compounding ingredient as typified by a rubbery polymer can be dispersed. The cyclic olefin ring-opening polymer can be obtained by ring-opening copolymerization of a cyclic olefin monomer mixture that contains trimers to pentamers of cyclopentadiene, and the trimers to pentamers of cyclopentadiene contain 55% or more of compounds, which are obtained in cases where n = 1-3, as geometrical isomers (2).
