Abstract
A golf ball and a method of making a golf ball, having a cover and a core, wherein the golf ball has at least one layer formed of a compatibilized blend of about 4 percent to 95 percent of at least one ionomer resin; about 95 percent to 4 percent of at least one non-ionic polymer; and about 1 to 15 phr, based on 100 parts ionomer resin and non-ionic polymer, of at least one non-carboxylic acid compatibilizer of functionalized block and graft polymers and oligomers, wherein at least one portion of the non-carboxylic acid compatibilizer is miscible with the at least one ionomer and at least one portion of the non-carboxylic acid compatibilizer is miscible with the at least one non-ionic polymer.
Claims23
A golf ball comprising a cover and a core, wherein the golf ball has at least one compatibilized layer formed of a compatibilized blend comprising:
- about 4 percent to about 95 percent of at least one ionomer resin comprising an ionomeric homopolymer or copolymer containing a polyester, polyamide, polyether, polycarbonate, or polyurethane, or an ionomeric homopolymer or copolymer consisting of a polyacrylate, an olefin and acrylic acid monomer, an olefin and methacrylic acid monomer, an olefin and a combination of acrylic acid and methacrylic acid monomers, or a mixture thereof;
- about 95 percent to about 4 percent of at least one non-ionic polymer selected from the group consisting of polyamide, polyester, and mixtures thereof;
- and
- about 1 to about 15 phr, based on 100 parts ionomer resin and non-ionic polymer, of at least one compatibilizer comprising a material, which is derived from a set of monomers that is substantially free of carboxylic acid-containing monomers and which is selected from the group consisting of block, random, and graft polymers, oligomers, and mixtures thereof, that are functionalized with moieties selected from the group consisting of epoxy, anhydride, oxazoline, and mixtures thereof,
- wherein at least a portion of the compatibilizer is miscible with the at least one ionomer and the at least one non-ionic polymer and wherein the at least one compatibilized layer is formed around the golf ball core.
A golf ball comprising a cover and a core, wherein the golf ball has at least one compatibilized layer formed of a compatibilized blend comprising:
- about 40 percent to about 90 percent of at least one ionomer resin;
- about 60 percent to about 10 percent of at least one non-ionic polymer selected from the group consisting of polyamide, polyester, and mixtures thereof;
- and
- about 1 to 15 phr, based on 100 parts ionomer resin and non-ionic polymer, of at least one compatibilizer comprising a material, which is derived from a set of monomers that is substantially free of carboxylic acid-containing monomers and which is selected from the group consisting of polyester-polyether block copolymers, polyamide-polyether block copolymers, polysiloxanes, silicones, styrene-butadiene and hydrogenated styrene-butadiene block co-polymers, olefinic block, random, and graft thermoplastic polymers and oligomers, which olefinic polymers or oligomers are functionalized with moieties selected from the group consisting of acid, ester, isocyanate, hydroxy, amine, and thiol, and mixtures thereof,
- wherein at least a portion of the compatibilizer is miscible with the at least one ionomer and the at least one non-ionic polymer and wherein the at least one compatibilized layer is formed around the golf ball core.
A golf ball comprising a cover and a core, wherein the golf ball has at least one compatibilized layer formed of a compatibilized blend comprising:
- about 4 percent to about 95 percent of at least one ionomer resin;
- about 95 percent to about 4 percent of at least one non-ionic polymer comprising a polyurethane;
- and
- about 1 to about 15 phr, based on 100 parts ionomer resin and non-ionic polymer, of at least one compatibilizer comprising a material, which is derived from a set of monomers that is substantially free of carboxylic acid-containing monomers and which is selected from the group consisting of functionalized block and graft polymers, oligomers, and mixtures thereof,
- wherein at least a portion of the compatibilizer is miscible with the at least one ionomer and the at least one non-ionic polymer and wherein the at least one compatibilized layer is formed around the golf ball core.
