Metallic monomer used as ionomeric additives for ionomers and polyolefins
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.
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.
2. The golf ball of claim 1 , wherein the metallic coagent is zinc cinnamate.
3. 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.
4. 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.
5. 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.
6. The golf ball of claim 5 , wherein the metallic coagent is zinc cinnamate.
7. The golf ball of claim 1 , wherein the intermediate layer comprises the ionomer.
8. 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.
9. The golf ball of claim 8 , wherein the metallic coagent is zinc cinnamate.
10. The golf ball of claim 1 , wherein the outer cover layer comprises the ionomer.
11. 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.
12. The golf ball of claim 11 , wherein the metallic coagent is zinc cinnamate.
