Abstract

A cyclopentene ring-opening polymer which has hydroxy groups at the polymer chain terminal ends is produced, then the hydroxy groups of the cyclopentene ring-opening polymer and isocyanate groups of a compound containing alkoxysilyl groups and isocyanate groups in its molecule are made to react to thereby produce a cyclopentene ring-opening polymer which contains structures at the polymer chain terminal ends where the polymer chains and groups including alkoxysilyl groups are bonded through urethane bond groups and which has a weight average molecular weight of 100,000 to 1,000,000.
