Abstract:
1. A core of a golf ball comprising an elastomeric interpolymer, wherein the interpolymer is prepared by a ring opening metathesis polymerization of 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 (T g ) of less than −80° C., and a number average molecular weight (M n ) of at least 40 kg/mole, each of the properties determined by the test procedures described herein, wherein the at least two cyclic olefin monomers are selected from the group consisting of cyclopropene, cyclobutene, benzocyclobutene, cyclopentene, norbornene, norbornadiene, cycloheptene, cyclooctene, 7-oxanorbornene, 7-oxanorbornadiene, cyclodecene, 1,3-cyclooctadiene, 1,5-cyclooctadiene, 1,3-cycloheptadiene, [2.2.1]bicycloheptenes, [2.2.2]bicyclooctenes, cyclohexenylnorbornenes, norbornene dicarboxylic anhydrides, cyclododecene, 1,5,9-cyclododecatriene, and a mixture thereof.
