Abstract
A golf ball is formed by molding a center of a homogeneous mass of polybutadiene with a metal salt of an unsaturated acid such as zinc dimethacrylate and a filler such as zinc oxide, and a cover of an ionic copolymer is formed about the center by coating as by electrodeposition or by molding. Molding of the center can successfully be carried out quickly above 170.degree. C. and the balls can be driven long distances. The centers can be molded with projections which are used for proper centering when molding a cover thereabout.
