Embodiments of the disclosed polymer composition comprise a first unsaturated polymer or polymer precursor, and an effective amount of a peptizer. The peptizer typically comprises a heteroaryl or a heterocyclic compound, other than morpholine as disclosed in assignee's prior applications. Disclosed polymer compositions are useful for making sports equipment, such as at least one layer of a golf ball, often a core. Because the compositions are useful for making golf balls, materials commonly known for making such golf balls can be used in combination with the polymer composition. A method for forming a golf ball also is disclosed. The method comprises providing disclosed compositions and then forming at least one component of a golf using the composition.

The present invention concerns reduced-yellowing thermoplastic or thermoset polymer compositions derived from the reaction of a diisocyanate, a polyol or polyamine, and a dicyandiamide. The present invention also concerns golf balls comprising the reduced-yellowing thermoplastic or thermoset polymer compositions derived from the reaction of a diisocyanate, a polyol or polyamine, and a dicyandiamide. The present invention also relates to a method for making a golf ball which includes using reduced yellowing compositions derived from the reaction of a diisocyanate, a polyol or polyamine, and a dicyandiamide. The resulting golf balls have similar processability and physical properties (such as resiliency and shear resistance) as golf balls made from conventional polyurethane or polyurea formulations, while exhibiting substantially improved resistance to yellowing.

The present invention relates to golf balls and golf ball components comprising a blend of one or more ionomers mixed with one or more metal or ammonium salts of chelating agent. The resulting modified ionomer compositions have improved proccessability as shown by the increase in melt flow index (12) as compared to the unmodified ionomer analogs while demonstrating an increase in resiliency or speed as shown by increasing COR, while maintaining or showing only a slight increase in hardness as measured by Shore D.
