A golf ball comprising of an outer core layer, or an inner cover layer having heat resistant properties to facilitate compression molding of a thermosetting polybutadiene-comprising layer over at least one thermoplastic layer. The ball comprises a thermoplastic inner core or core layer 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 an outer adjacent thermoset layer is placed around the inner core or core layer, the thermoset layer comprising comprising a peroxide that decomposes at low temperatures forming free radical initiators with short half lives, therein reducing the molding temperature of the high vicat layer and subsequently reducing the temperature and/or time the softer thermoplastic layer is exposed to the high heat.
