Abstract
The invention provides a golf ball material composed of an ionomeric resin composition obtained by melt-blending under applied heat one or more compounds selected from among UV/EB-curable materials with, in the presence of a peroxide, a non-ionomeric thermoplastic resin and an ionomeric resin; or of an ionomeric resin composition obtained by using, instead of the ionomeric resin, an acid-containing polymer base of the ionomeric resin and subjecting the acid-containing polymer composition similarly prepared by melt-blending under applied heat to an acid-neutralizing reaction with a metal ionic species. Methods for preparing such a material, and golf balls which include as a component therein a molding made of the golf ball material are also provided. The golf ball material has a good thermal stability, flow and processability, and can thus be used to obtain high-performance golf balls endowed with an excellent abrasion resistance, scuff resistance, durability and flexibility without a loss of rebound.
