Patent ID: 7915375

Claim:
A copolymer produced by metathesis polymerization of two distinct monomer, where the two monomer include (i) 1,5-cyclooctadiene and cyclopentene, (ii) 1,5-cyclooctadiene and cyclooctene, or (iii) cyclooctene and cyclopentene, where the copolymer includes at least one or more terminal functional groups selected from the group consisting of hydroxyl, carboxylic acid, ester, carbonate, cyclic carbonate, anhydride, cyclic anhydride, lactone, amine, amide lactam, cyclic ether, ether, aldehyde, thiazoline, oxazoline, phenol, and melamine functional groups, where the copolymer includes less than about 2% pendant vinyl groups, from about 5 to about 25 double bonds per 100 carbon atoms, and has a cis content that is greater than 10%.
