Abstract
A golf ball having an improved low temperature impact resistance, which comprises a core and a cover made of a cover composition containing an ionic copolymer having at least two different metal ions in one molecule. The cover composition is prepared by kneading a sodium ion type ionic copolymer having free carboxyl groups and a metal oxide such as magnesium or zinc oxide at high temperatures, whereby the metal oxide is reacted with the ionic copolymer to incorporate the metal ion such as magnesium or zinc ion into the ionic copolymer.
