Abstract
A cyclopentene ring-opening polymer having, at a polymer chain end, a structure where a polymer chain and a group containing an alkoxysilyl group are bonded through —NH— and having a weight average molecular weight of 100,000 to 1,000,000, wherein the structure is a structure represented by the following general formula (1):pCP—Y1-NH—Y2-Si(OR1)a(R2)3-a  (1)where, in the general formula (1), pCP represents a cyclopentene ring-opening polymer chain, Y1 represents a bivalent hydrocarbon group having 1 to 20 carbon atoms, each of R1 and R2 represents a hydrocarbon group having 1 to 20 carbon atoms, Y2 represents a bivalent hydrocarbon group having 1 to 20 carbon atoms in which —NH— may be interposed, and 'a' is an integer of 1 to 3.
