  • Patent number: 4100182
    Abstract: An adjuvant for an elastomeric composition is made by mixing methacrylic acid with a suspension of zinc oxide in a liquid medium (such as water or alcohol) in the proportions required to form basic zinc methacrylate. Removal of the liquid from the reaction product and blending of the finely divided reaction product with an elastomer such as cis-polybutadiene yields a compositon which, when cured (for example with an organic peroxide), is hard yet resilient. Molding of the composition in the form of a golf ball produces a durable solid golf ball which has in large measure the play characteristics of a wound golf ball, and substantially retains such characteristics after extended play.
