摘要:The present invention provides a polymer composition which includes (A) an olefin-unsaturated carboxylic acid random copolymer and/or an olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester random copolymer, (D) a metal ion neutralization product of an olefin-unsaturated carboxylic acid random copolymer and/or a metal ion neutralization product of an olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester random copolymer, or both components A and D, and also includes a specific amount of (B) a metal oxide which is capable of neutralizing acid groups in components A and/or D, and which is produced by plasma synthesis, laser synthesis or flame synthesis and has an average particle diameter of at most 200 nm. The invention also provides golf balls in which such a polymer composition serves as a component of the ball. The polymer composition is ionically bonded and has an excellent resilience. Golf balls made using the polymer composition have an outstanding rebound.
