[PROBLEMS] To provide a novel material having properties equivalent to or better than those of prior art ionomer resins used in golf ball manufacture, but not plastic, and more compatible with other resins, and to provide a hard feel to golf balls. To provide a novel material that does not give, or is brittle, not prone to breakage, and does not require the addition of a softer terpolymer ionomer. A blend composition comprising reaction products of three components (A), (B) and (C) is provided. Component (A) is a polymer comprising ethylene and / or α-olefin and one or more α, β-ethylenically unsaturated C 3 -C 20 carboxylic acid, sulfonic acid or phosphoric acid. Component (B) has the general formula (R 2 N) m -R ' - (X (O) n OR y) is a compound having m, acidic component (C) is present in the component (A) and (B) A basic metal ion salt having the ability to neutralize some or all of the groups.
