Abstract
The present invention is directed to a multi-layer golf ball having a core, an intermediate layer and a cover. The intermediate layer has a non-ionomeric composition that includes an ethylene/acid polymer and a non-ionomeric stiffening polymer. The stiffening polymer provides the non-ionomeric composition with a flexural modulus and a hardness that are greater than those of the ethylene/acid polymer.
Claims21
A golf ball comprising a core, a cover, and an intermediate layer therebetween consisting essentially of a non-ionomeric composition comprising (a) an acid copolymer or terpolymer having a formula of E/Y or E/X/Y, where E is an olefin, Y is a carboxylic acid and X is a softening comonomer, and (b) a non-ionomeric stiffening polymer, wherein the acid copolymer or terpolymer has a first flexural modulus and a first material hardness, and wherein the non-ionomeric composition has a second flexural modulus and a second material hardness substantially greater than the first flexural modulus and the first material hardness.
A golf ball comprising a core, a cover, and a intermediate layer therebetween consisting essentially of a non-ionomeric composition comprising (a) a blend of a first and second acid copolymers, each having a formula of E/Y or E/X/Y, where E is an olefin, Y is a carboxylic acid and X is a softening comonomer, and (b) a non-ionomeric stiffening polymer, wherein the acid polymer blend has a first flexural modulus and a first material hardness;
- and wherein the non-ionomeric composition has a second flexural modulus and a second material hardness substantially greater than the first flexural modulus and the first material hardness.
