GOLF BALL COMPOSITIONS

摘要

Disclosed herein are heterogeneous golf ball compositions comprising a matrix formed from a thermosetting or thermoplastic polymer composition and discrete particles dispersed within the matrix, and to the use of such heterogeneous compositions to form at least one core layer in multi-layer core golf balls.

主权项

1. A golf ball comprising a core and a cover, wherein the core comprises:
an inner core layer formed from a first thermoset composition and having a diameter of from 0.50 inches to 1.30 inches; an intermediate core layer formed from a heterogeneous composition and having a thickness of from 0.01 inches to 0.20 inches; and an outer core layer formed from a second thermoset composition and having a thickness of from 0.10 inches to 0.25 inches; wherein the heterogeneous composition of the intermediate core layer comprises a matrix formed from a first thermoplastic composition and discrete particles of a second thermoplastic composition dispersed within the matrix, the second thermoplastic composition having a melting point above the processing temperature of the first thermoplastic composition.
