Abstract:
1. A golf ball comprising a plurality of members which include: (I) a first member comprised of a material molded under heat from a rubber composition comprising (a) a base rubber composed primarily of a mixture of at least 60 wt % of a polybutadiene having a stress relaxation time (T (II) a second member formed primarily of a resin composition obtained by mixing wherein (i) the olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester random terpolymer and/or a metal salt thereof serving as component A-I has a weight-average molecular weight (Mw) of at least 100,000 but not more than 200,000, and a weight-average molecular weight (Mw) to number-average molecular weight (Mn) ratio of at least 3 but not more than 7.0, and (ii) the olefin-unsaturated carboxylic acid random copolymer and/or a metal salt thereof serving as component A-II has a weight-average molecular weight (Mw) of at least 150,000 but not more than 200,000, and a weight-average molecular weight (Mw) to number-average molecular weight (Mn) ratio of at least 3 but not more than 7.0.
