US Patent 7332533 - Golf ball with evenly distributed nanofiller

This patent discloses evenly dispersed nanoparticles to optimize the controllability as well as other parameters of a golf ball. Claim 1 reads:

1. A golf ball comprising: 1) a core; a 2) an intermediate layer; and 3) a cover layer; wherein the core comprises: a) a matrix polymer selected from the group consisting of thermoplastics, thermosets and combinations thereof, b) particles of one or more nanofillers, and c) a compatibilizing agent coated on the surfaces of the nanofiller particles, selected to ensure that the nanofiller particles are substantially evenly dispersed in said matrix polymer.
