Patent ID: 8362149

Claim:
A method for preparing a golf ball material, comprising the steps of: initially melt-blending (i) at least one compound selected from among UV/EB-curable materials wherein a portion of a main-chain skeleton of the compound is selected from the group consisting of polyester, polyether, urethane, acrylate, butadiene, epoxy, carbonate and rosin structures, and which have at least two functional groups with an ethylenically unsaturated bond per molecule, the functional groups with an ethylenically unsaturated bond being polymerizable functional groups of one or more types selected from the group consisting of acrylic (CH 2 ═CHCO—), methacrylic (CH 2 ═C(CH 3 )CO—), allyl (CH 2 ═CHCH—) and vinyl (CH 2 ═CH—) groups with (ii) a non-ionomeric thermoplastic resin; then adding (iii) an ionomeric resin or an ionomeric resin together with the acid-containing polymer base thereof and melt-blending so as to obtain an ionomeric resin composition.
