Abstract:
1. A method of forming at least a portion of a golf ball core which comprises: mixing a resilient polymer component, a free-radical initiator, and a reinforcing polymer component to provide an uncrosslinked first mixture having a flexural modulus greater than about 3.5 MPa; forming the first mixture into a plurality of shells in a desired shape, wherein the reinforcing polymer component imparts sufficient rigidity to the shells to maintain the desired shape until the first mixture is crosslinked; providing a center; assembling at least two shells from the plurality of shells concentrically about the center to form a first mantle layer, wherein the first mantle layer and center together form the golf ball core; and applying sufficient heat and pressure to the core for a time sufficient to at least partially crosslink the first mixture in the at least two shells, thereby curing at least a portion of the golf ball core.
