Golf ball and method of manufacturing thereof

摘要

A golf ball and a method of manufacturing thereof are provided, the golf ball having a core containing a Mg vulcanized rubber powder crosslinked by a magnesium salt of an unsaturated carboxylic acid and another vulcanized rubber powder crosslinked by a co-crosslinking agent other than the magnesium salt of the unsaturated carboxylic acid. Preferably, the ratio alpha/beta between the content alpha of the Mg vulcanized rubber powder and the content beta of another vulcanized rubber powder is 1/4 to 4, and the total content alpha+beta of the vulcanized rubber powders based on 100 parts by mass of a base rubber of the core is 5 to 30 parts by mass.
