A composition suitable for preparing a golf ball core, comprises: an elastomer cross-linkable by a free radical initiator catalyst or any other suitable catalyst; a metal salt or ester of an alpha, beta ethylenically unsaturated monocarboxylic acid compound, or any mixture thereof; a free radical initiator catalyst or any other suitable catalyst, for cross-linking said elastomer and said metal salt or ester compound, and a polyfunctional isocyanate optionally having 3 to 30 carbon atoms. he polyfunctional isocyanate enables an increase in coefficient of restitution of a golf ball comprising a core made from such composition to be obtained.
