| 主权项 | 1. A ring-opening polymer of cyclopentene, wherein a cis ratio of cyclopentene-derived structural units in the ring-opening polymer is 30% to 95%, a weight average molecular weight (Mw) is 100,000 to 1,000,000, and a functional group containing a structure represented by the following general formula (1) or (2) is included at an end of the polymer chain: —Y—H (1), wherein Y represents an oxygen atom or a sulfur atom and —NH-Q (2), wherein Q represents a hydrogen atom or a hydrocarbon group or a silyl group which may have a substituent group. | ||
