Patent abstract
The present invention is directed to a golf ball comprising a shield layer having heat resistant properties to facilitate compression molding of a thermosetting polybutadiene-comprising layer over at least one thermoplastic layer. The invention utilizes a thermoplastic inner core comprising of a low vicat highly neutralized ionomer material having a low melting point of less than 100° C., and a Shore C surface hardness of less than 80 and a compression of less than 70, wherein a shield layer is placed around the low vicat softening point temperature thermoplastic to shield it from the high heat necessary to mold a thermoset material about it.
