## Abstract

A golf ball comprising: (a) a core: (b) an outer cover layer; and (c) optionally, at least one intermediate layer, wherein at least the outer cover layer or the intermediate layer comprises a blend composition of: (i) a metallic coagent; and (ii)(a) at least one polyolefin or (ii)(b) at least one ionomer.

## Claims

### Claim 1

A golf ball comprising:
(a) a core:
(b) an outer cover layer; and
(c) optionally, at least one intermediate layer,
wherein at least the outer cover layer or the intermediate layer comprises an ionomer made by blending a metallic coagent with a non-neutralized copolymeric or terpolymeric olefin-containing acid, wherein the metallic coagent is zinc cinnamate, zinc hydrocinnamate, zinc naphthalene acetate, or zinc naphthoate.

### Claim 2 (depends on 1)

The golf ball of claim 1, wherein the metallic coagent is zinc cinnamate.

### Claim 3 (depends on 1)

The golf ball of claim 1, wherein the amount of the metallic coagent is at least 1 wt%, based on the total weight of the ionomer.

### Claim 4 (depends on 1)

The golf ball of claim 1, wherein the amount of metallic coagent blended is not greater than 40 wt%, based on the total weight of the ionomer.

### Claim 5 (depends on 1)

The golf ball of claim 1, wherein the non-neutralized copolymeric or terpolymeric olefin-containing acid is selected from an ethylene/(meth)acrylic acid copolymer, an ethylene/(meth)acrylic acid/alkyl (meth)acrylate terpolymer, or an ethylene and/or propylene maleic anhydride copolymer or terpolymer.

### Claim 6 (depends on 5)

The golf ball of claim 5, wherein the metallic coagent is zinc cinnamate.

### Claim 7 (depends on 1)

The golf ball of claim 1, wherein the intermediate layer comprises the ionomer.

### Claim 8 (depends on 7)

The golf ball of claim 7, wherein the non-neutralized copolymeric or terpolymeric olefin-containing acid is selected from an ethylene/(meth)acrylic acid copolymer, an ethylene/(meth)acrylic acid/alkyl (meth)acrylate terpolymer, or an ethylene and/or propylene maleic anhydride copolymer or terpolymer, and the metallic coagent is a metal cinnamate.

### Claim 9 (depends on 8)

The golf ball of claim 8, wherein the metallic coagent is zinc cinnamate.

### Claim 10 (depends on 1)

The golf ball of claim 1, wherein the outer cover layer comprises the ionomer.

### Claim 11 (depends on 10)

The golf ball of claim 10, wherein the non-neutralized copolymeric or terpolymeric olefin-containing acid is selected from an ethylene/(meth)acrylic acid copolymer, an ethylene/(meth)acrylic acid/alkyl (meth)acrylate terpolymer, or an ethylene and/or propylene maleic anhydride copolymer or terpolymer, and the metallic coagent is a metal cinnamate.

### Claim 12 (depends on 11)

The golf ball of claim 11, wherein the metallic coagent is zinc cinnamate.
