    • PROBLEM TO BE SOLVED: To provide a golf ball which includes a layer formed from a relatively soft HNP composition and a layer formed out of a relatively hard HNP composition. SOLUTION: The golf balls have at least three layers, including an inner core layer, an outer core layer, and optionally an intermediate core layer. The present invention is not limited by which golf ball layers are formed from an HNP composition, so long as at least one layer is formed from a relatively soft HNP composition and at least one layer is formed from a relatively hard HNP composition. Relatively soft HNP compositions comprise a highly neutralized acid copolymer preferably having a modulus in the range from 1,000 psi to 50,000 psi. Relatively hard HNP compositions comprise a highly neutralized acid copolymer preferably having a modulus in the range from 25,000 psi to 150,000 psi. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种高尔夫球,其包括由相对柔软的HNP组合物形成的层和由相对硬的HNP组合物形成的层。 解决方案:高尔夫球具有至少三层,包括内核层,外芯层和任选的中间核心层。 本发明不限于此,由HNP组合物形成高尔夫球层,只要由相对较软的HNP组合物形成至少一层,并且由相对较硬的HNP组合物形成至少一层。 相对软的HNP组合物包含优选具有1,000psi至50,000psi范围内的模量的高度中和的酸共聚物。 相对硬的HNP组合物包含优选具有在25,000psi至150,000psi范围内的模量的高度中和的酸共聚物。 版权所有(C)2009,JPO&INPIT
