A multiple layer golf ball having a high compression core and a soft boundary layer is disclosed herein. The multiple layer golf ball may also have a hard cover. The soft boundary layer allows the multiple layer golf ball to mimic the properties of a lower compression core while providing good distance. The multiple layer golf ball has a low driver spin and a high pitching wedge spin. The boundary layer is composed of a polyurethane formed from a PPDI-based prepolymer while the core is composed of a polybutadiene. The cover may be composed of an ionomer blend. |
