Abstract
Disclosed herein is a golf ball comprising a polyurethane component formed by the reaction of an isocyanate, and a polyether polyol comprising homopolymers of ethylene oxide or propylene oxide or copolymers thereof, and a curing agent/chain extender. Another preferred form of the invention is directed to a golf ball cover comprising an isocyanate component and an ethylene/propylene oxide polyether polyol polyurethane component that is formed by reaction injection molding.
