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 polyol that is a homopolymer of propylene oxide having a molecular weight greater than 1000; andC) 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.
