Abstract
The invention provides a molded polymer material which is obtained by subjecting a polymer composition that includes (A) at least one polymer containing α,β-ethylenically unsaturated carboxylic acid, (B) at least one diene polymer, (C) at least one metal cation source, and (D) at least one organic peroxide, and has a chemical structure arrived at by neutralizing some or all of the carboxyl groups in component A with component C in the presence of component B, to molding and crosslinking under the influence of radicals generated by decomposing component D. The molded polymer material has a high resilience, a high hardness and a good durability, making it well-suited for use in golf balls.
