<p>A multiple layer golf ball (10) having a high compression core (12) and a soft boundary layer (16) is disclosed herein. The multiple layer golf ball (10) may also have a hard cover (14). The soft boundary layer (16) allows the multiple layer golf ball (10) to mimic the properties of a lower compression core while providing good distance. The multiple layer golf ball (10) has a low driver spin and a high pitching wedge spin. The boundary layer (16) is composed of a polyurethane formed from a PPDI-based prepolymer while the core (12) is composed of a polybutadiene. The cover (14) may be composed of an ionomer blend.</p> |
