Multi-layer golf ball providing improved speed

A golf ball comprising:

• a. a core;
• b. an intermediate layer;
• and
• c. a cover layer;
• d. wherein said intermediate layer comprises a modified ionomeric polymer comprising:
• a bimodal polymer blend composition comprising:
• (1) a high molecular weight component having molecular weight of about 80,000 to about 500,000 and comprising one or more ethylene/α,β-ethylenically unsaturated C3-8 carboxylic acid copolymers and/or one or more ethylene, alkyl(meth)acrylate, (meth)acrylic acid terpolymers;
• said high molecular weight component being partially neutralized with metal ions selected from the group consisting of lithium, sodium, zinc, calcium, magnesium, and a mixture of any these, and
• (2) a low molecular weight component having a molecular weight of about from about 2,000 to about 30,000 and comprising one or more ethylene/α,β-ethylenically unsaturated C3-8 carboxylic acid copolymers and/or one or more ethylene, alkyl(meth)acrylate, (meth)acrylic acid terpolymers;
• said low molecular weight component being partially neutralized with metal ions selected from the group consisting of lithium, sodium, zinc, calcium, magnesium, and a mixture of any these, and
• (3) about 5 to about 45 weight percent (based on the total weight of said modified ionomeric polymer) of a fatty acid or one or more metal salts of said fatty acid;
• wherein about 40 to 100 percent of the acid groups present in said modified ionomeric polymer are neutralized with zinc, sodium, lithium, calcium, or magnesium ions, or a combination thereof;
• e. wherein said core has a diameter in the range of about 1.20 to about 1.56 in. and a
• PGA compression in the range of about 40 to about 90;
• f. wherein said intermediate layer has a thickness in the range of about 0.01 to about 0.10 in. and a Shore D hardness in the range of about 30 to about 75;
• g. and wherein said cover layer has a Shore D hardness in the range of about 40 to about 70.
