Elastomers, process for preparation, and uses thereof

A rubber composition comprising an elastomeric compound comprising at least two cyclic olefin monomers, wherein the interpolymer is prepared by a ring opening metathesis polymerization of the at least two cyclic olefin monomers and wherein the interpolymer is characterized by having a crystallinity of 0 to about 30%, a glass transition temperature (Tg) of less than −80° C., and a number average molecular weight (Mn) of at least 40 kg/mole, each of the properties determined by the test procedures described herein.

An interpolymer comprising:

• the metathesis polymerization product of at least two distinct cyclic olefin monomers, where the at least two distinct cyclic olefin monomers are selected from the group consisting of yclopentane, cyclooctene, 1,3-cyclooctadiene, 1,5-cyclooctadiene, 1,3-cycloheptadiene, and 1,5,9-cyclododecatriene, where the interpolymer is characterized by having no crystallinity, a glass transition temperature (Tg) of less than −80° C., and a number average molecular weight (Mn) of at least 40 kg/mole, and where the interpolymer includes at least one functional group selected from the group consisting of carboxylic acid, a nitrile, an amine, an amide, an ester, a sulfonate, a metal salt of a carboxylic acid, succinic anhydride, a hydroxyl, and combinations thereof.
