    • The present invention provides a golf ball having high rebound characteristics and exceptional controllability at approach shot from the rough, which accomplished by controlling its cover material morphology. The present invention relates a golf ball comprising a core and a cover covering the core, wherein the base resin of the cover is formed from a material having at least two phases whose phase angle difference is at least 2 degrees as measured by using an atomic force microscope; a maximum phase angle phase, which is contained in the base resin of the cover and has an absolute value of a maximum phase angle, is present in the form of a continuous matrix; and a minimum phase angle phase, which has an absolute value of a minimum phase angle, is present in discrete locations within the matrix.
    • 本发明提供了一种具有高回弹特性的高尔夫球,并且通过控制其覆盖材料的形态来实现从粗糙的接近射击时的出色的可控性。 本发明涉及一种高尔夫球,其包括芯和覆盖芯的盖,其中盖的基础树脂由具有至少两个相的材料形成,其相位角差为至少2度,通过使用原子力 显微镜; 包含在盖的基础树脂中并且具有最大相位角的绝对值的最大相位角相位以连续矩阵的形式存在; 并且具有最小相位角的绝对值的最小相位角相位存在于矩阵内的离散位置中。
