Functional Cyclic Olefin Polymer, Process for Obtaining the Same and Compositions Containing the Same

(canceled)

A composition, comprising a functional cyclic olefin polymer obtained from hydrogenation of a cyclic olefin polymer, wherein the cyclic olefin polymer comprises at least a monomeric unit A′ derived from a monomer A having a norbornene ring and a polar functional group, wherein the polar functional group is selected from hydroxy, hydroxyalkyl group, hydroxyaryl group, carboxyl, alkylcarbonyloxy, arylcarbonyloxy, aryloxycarbonyl, alkoxycarbonyl such as —COOCH3, or a combination thereof, wherein the amount of the monomeric unit A′ is in the range from 20% to 100% by mole, 50% to 100% by mole, from 60% to 100% by mole, or from 70% to 100% by mole, based on the total amount of the monomeric units of the cyclic olefin polymer.
