  • Patent number: 8932151
    Abstract: The invention provides a solid golf ball having a core and a cover. The core is formed of a rubber composition containing a base rubber, a co-crosslinking agent, a crosslinking initiator and a metal oxide. The base rubber contains polybutadiene, a styrene-butadiene rubber and, optionally, an isoprene rubber. The co-crosslinking agent is methacrylic acid, and the rubber composition includes a specific waste material in the form of a powder. The core deflection and the cover material are optimized. Utilizing a waste material in a solid golf ball conserves resources and thus is beneficial to the global environment. Even during prolonged use, the golf ball maintains its basic performance attributes (feel, flight, durability) at a high level.

  • Patent number: 7638576
    Abstract: According to the present invention, aqueous multi-stage polymer dispersions comprising an acid-functional first polymer and an epoxy-functional second polymer, wherein 90 mole % or more of the said epoxy groups, based on the moles of epoxy groups in the monomer mixture used to form the second polymer, are retained in the aqueous dispersion after said dispersion is stored in a sealed container for 10 days at 60° C. Further, methods of making the aqueous multistage polymer dispersion comprise polymerizing the monomers used to make the second polymer in the presence of an aqueous dispersion of the first polymer. Preferably, the second polymer is formed in the presence of 0.3 wt. % or less, based on the total weight of the first polymer and the ingredients to form the second polymer, of one or more strong acid surfactant, and 3) 0.1 wt.
