Abstract: A method of making and recycling a golf ball is disclosed. The method may include processing a used golf ball to make the materials of the used golf ball reusable in a new golf ball. As a result, the disclosed method may decrease the waste of disposing of used golf balls and the costs associated with acquiring and/or processing new materials. The method of recycling a golf ball may generally include pulverizing used golf balls into particles. The used golf balls may be made of materials having different densities. The particles may be placed in a liquid that causes the particles of different materials to float to different levels based on the densities of the materials. At least a portion of the particles may be melted and injected into a sandwich mold to create a new golf ball.

Abstract: Alternate characterizations of golf ball striking ability is provided, as well as methods for determining the alternate characterizations and systems for carrying out such determinations. Such methods may include performing one or more golf strikes to impart trajectories to one or more golf balls. Such methods may also include measuring each of the golf strikes to determine golf club head, golf ball speed, side spin angle, and offline angle, calculating a trajectory magnitude factor and a trajectory offline factor on the basis of the measurements, and reducing the trajectory magnitude factor by the trajectory offline factor.

Abstract: This disclosure relates to golf balls having a cover layer made from a crosslinked thermoplastic polyurethane elastomer. The crosslinked thermoplastic polyurethane elastomer includes crosslinks located in the hard segments, where the crosslinks being the reaction product of unsaturated bonds located in the hard segments catalyzed by a free radical initiator. The crosslinks may be formed from an unsaturated diol as a chain extender. The unsaturated diol may be trimethylolpropane monoallylether (TMPME). The cover layer may have certain properties, such as a desirable flexural modulus value and a desirable Shore D hardness value, that further contribute to the golf ball having a high degree of scuff resistance.
