Abstract
Abstract One-piece, nonhomogeneous, molded golf ball is obtained by forming a center of an uncured elastomeric material, surrounding the center with a compatible but different uncured elastomeric material, and curing both elastomeric materials, such that when said materials are cured they become integral with each other to form an one-piece molded golf ball which is harder at its center than at its outer surface.
