Zusammenfassung:Provided is a liquid cyclopentene ring-opened copolymer comprising a monomer unit derived from cyclopentene and a monomer unit derived from a norbornene compound, the monomer unit derived from cyclopentene being present in an amount of 60 to 95 wt%, the liquid cyclopentene ring-opened copolymer having a hydroxyl group-terminated copolymer chain and having a melt viscosity at 25°C of less than 500 Pa·s, which is measured using a B-type viscometer.
