Title: Low cost, resilient, shear resistant polyurethane elastomers for golf ball covers

Abstract: Disclosed herein is a golf ball comprising a core and a cover, said cover comprising a polyurethane elastomer comprising the reaction product of: A) at least one diisocyanate monomer; B) at least one polyether polyol having a molecular weight greater than 1000 and selected from the group consisting of homopolymers of ethylene oxide, homopolymers of propylene oxide, and copolymers of ethylene oxide and propylene oxide; and C) at least one hydroxy or amine functional chain extender; wherein the ratio of equivalents of chain extender plus polyol to equivalents of isocyanate is in the range of from about 0.6:1 to about 1.2:1, whereby said polyurethane elastomer possesses high shear resistance and good resilience.
