Golf balls that have at least one layer formed from a cationic polyurea material. In particular, the compositions of the invention, which include a polymer backbone including urea linkages with cationic groups, may be formed from an isocyanate-containing component and an isocyanate-reactive component, at least one of which includes precursor cationic groups, in the presence of an alkylating, quaternizing, or ternarizing agent.

Cationic polyurea cover compositions for a multi-layer golf ball

Compositions for golf balls including modified highly neutralized polymeric compositions that have improved processability including improved melt flow index and improved performance characteristics when included in a layer of a golf ball. In addition, the compositions of the invention have less moisture transmission and higher flexural modulus than non-modified highly neutralized polymers.

Highly neutralized polymeric compositions for golf ball layers

Golf ball compositions including a rosin-modified polymeric composition including a conventional ionomer, acid copolymer, highly neutralized polymer, or other suitable polymer that has been modified with a rosin material to impart stiffness through increasing the flexural modulus of the material.

Golf balls incorporating rigid, rosin-modified polymers

A golf ball including a core having a first outer surface; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer including a non-ionic hydrophobic stiff fluoropolymer having a surface energy of less than about 75 dyne/cmand having a second outer surface; wherein at least one of the first or second outer surfaces are treated with an functional silane such that a sufficient number of surface amine, hydroxyl, carboxylic acid, or epoxy groups are available for binding to an adjacent layer.

Non-ionic fluoropolymer inner layer with improved adhesion

A golf ball comprising a core having a first density formed from a diene rubber composition including glass microspheres having an isotactic crush strength of about 5,000 psi or greater and having a true density of about 0.70 g/cmor less, the microspheres being present in an amount sufficient to lower the first density to about 1.05 g/cmor less; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer having a density of from about 1.3 g/cmto about 1.9 g/cmand including a composition formed from a compatibilized blend of a non-ionic fluoropolymer and an acrylate-based polymer; wherein a ratio of the core density to the intermediate layer density is between about 0.81 to about 0.5.
