    • 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.
    • 一种高尔夫球,其包括外芯层或具有耐热性能的内覆盖层,以便于在至少一个热塑性层上压缩模制含热固性聚丁二烯的层。 该球包括热塑性内芯或芯层,该热塑性内芯或核心层包含低维氏度高度中和的离聚物材料,其低熔点小于100℃,肖氏C表面硬度小于80,压缩度小于70, 其中外部相邻的热固性层被放置在所述内部芯或芯层周围,所述热固性层包括包含在低温下分解形成具有短半衰期的自由基引发剂的过氧化物,其中降低所述高维卡层的成型温度并随后还原 较软的热塑性层暴露于高热的温度和/或时间。
