Abstract
The present invention discloses a hydrogenated ring-opening metathesis polymer comprising at least unit (A) of formula (1), unit (B) of formula (2) and unit (c) of formula (3): wherein a constituent molar ratio of the structural unit (A)/(B) is from 1/99 to 99/1 and a constituent molar ratio of the structural unit (B)/(C) is from 30/70 to 100/0 and, furthermore, a ratio of a weight-average molecular weight Mw to a number-average molecular weight Mn, that is Mw/Mn is from 1.0 to 2.0.
