An objective of the present invention is to provide a resin composition which gives a molding excellent in flexibility, impact resilience and mechanical properties and a golf ball having the better shot feel, a long carry, and the excellent cutting resistance when used in a golf ball cover. The resin composition of the present invention is characterized in comprising an ionomer resin, an alkoxysilyl group-containing hydrogenated conjugated diene-based polymer and/or an amino group-containing hydrogenated conjugated diene-based polymer. Alkoxysilyl group content and amino group content in the above-mentioned polymers are preferably 0.0001 to 5 mmol/g, respectively. The golf ball of the invention is characterized in that core is covered with a cover material using the above-mentioned resin composition.
A resin composition comprising (a) an ionomer resin, (b) an alkoxysilyl group-containing hydrogenated conjugated diene-based polymer and (c) an amino group-containing hydrogenated conjugated diene-based polymer.
A golf ball whose core is covered with a cover material comprising a resin composition comprising (a) an ionomer resin, (b) an alkoxysilyl group-containing hydrogenated conjugated diene-based polymer, and (c) an amino group-containing hydrogenated conjugated diene-based polymer.
A resin composition comprising (a) an ionomer resin and (b) a hydrogenated conjugated diene-based polymer having both alkoxysilyl groups and amino groups.
A golf ball whose core is covered with a cover material comprising a resin composition comprising an ionomer resin and a hydrogenated conjugated diene-based polymer having both alkoxysilyl groups and amino groups.
