Golf ball

Abstract

Disclosed is a two-piece golf ball and methods for its production. The ball comprises a core having a central portion of a cross-linked, hard, resilient material and having a soft, deformable outer layer. Balls comprising the novel cores and a conventional cover material having playability properties approaching or exceeding thread-wound balata covered balls. The core is preferably manufactured by surface treating a slug of a suitable, curable elastomer composition with a cure altering agent, and molding the slug under conditions to produce a spherical core having a hardness gradient in its surface layers.
