Abstract
A novel copolymer is obtained by reacting [A] at least one norbornene derivative having at least one polar group or polar-group-containing substituent with [B] at least one unsaturated polymer having carbon-to-carbon double bonds in the presence of a metathesis catalyst. This copolymer is excellent in chemical and mechanical properties. Particularly, when 50% by weight or more of the component [A] is contained, the resin is distinguished for its high impact strength.
