Golf ball composition and golf ball

摘要

The invention provides a golf ball composition containing an ionomer resin composition of: (A) one or more ionomer selected from the group consisting of an olefin-unsaturated carboxylic acid random copolymer and/o2r an olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester random copolymer, and 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; (B) a polyethylene; and (C) an organic peroxide.

1. A golf ball composition comprising a resin composition which is comprised of:
(A) one or more acid-containing polymers selected from the group consisting of an olefin-unsaturated carboxylic acid random copolymer and/or an olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester random copolymer, and 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; (B) a high-pressure low-density polyethylene; and (C) an organic peroxide, wherein, letting Pi be the surface area of a peak that appears in the range of 43 to 56° C. when measuring the resin composition with a differential scanning calorimeter and Pz be the surface area of a peak that appears in the range of 43 to 56° C. when measuring the same resin composition, exclusive of component C, with a differential scanning calorimeter, the golf ball composition satisfies the following condition:
