Abstract
The present invention provides an ionomer composition for a golf ball providing a golf ball which is excellent in abrasion-resistance, durability and resilience, and a golf ball using the same. An ionomer composition for a golf ball of the present invention comprises a binary copolymer obtained by copolymerizing an olefin monomer having 2 to 8 carbon atoms with an unsaturated monomer having an acid functional group and/or a ternary copolymer obtained by copolymerizing an olefin monomer having 2 to 8 carbon atoms, an unsaturated monomer having an acid functional group and an unsaturated carboxylic acid ester, wherein a functional group is introduced in both terminals of the copolymers.
