Patent ID: 7888448

Claim:
A method of forming a portion of a golf ball comprising the steps of: providing a first polymeric precursor formed from the reaction product of a half-blocked intermediate and an amine-terminated component, wherein the half-blocked intermediate is the reaction product of an isocyanate having terminal isocyanate groups and a first curing agent comprising a blocked, delayed action curative; providing a second polymeric precursor comprising an acrylate resin; adding a second curing agent to the second polymeric precursor to form a second polymeric system; combining the first polymeric precursor and second polymeric system in a vessel; elevating the temperature in the vessel to an amount sufficient to unblock the first curing agent to provide a first polymeric system resulting in an interpenetrating polymer network (“IPN”) comprising the first and second polymeric systems; and forming the IPN into the portion of the golf ball.
