  • Patent number: 6596797
    Abstract: The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polyubutadiene compositions are composed of polypropylene powder resins which have the effect of increasing the hardness of the resulting molded cores without increasing the weight upon curing, thereby allowing for a reduction in the amount of crosslinking agents utilised and increasing the amount of fillers incorporated therein. The addition of the polypropylene powder resins to the core compositions lowers the cost of the molded core, while maintaining the proper weight and compression. The present invention is also directed to golf balls produced utilizing the improved core compositions. Furthermore, the invention is directed to a method for reducing the amount of crosslinking agents utilized to formulate a core composition through the incorporation of polypropylene powder resins.

  • Patent number: 5891948
    Abstract: One-coating and one-package type coating material in which wall surfaces or the like of a building are finished into natural granite tone are disclosed. A group of flexible resin flakes having more than three kinds of colors and a binder which is turned to be substantially transparent when dried or set are mixed together. The resin flakes have an irregular shape and a random size, the thickness is uneven within one piece and every one piece, having a peripheral end which becomes continuously thin toward the outer edge, and have a color tone similar to the components of granite. Since the peripheral end of the resin flakes is continuously thin toward the outer edge, when coated, there is no unnatural difference in level in the superposed portions of resin flakes. Further, an external appearance and a quality sense extremely close to natural granite are obtained due to the unevenness of thickness of resin flakes.

  • Patent number: 5880183
    Abstract: A composition of a hydroxyl functional polymer, an acetate functional polymer and a carboxyl functional polymer, which are crosslinked by a polyfunctional aziridine. Preferably, PVOH, polyvinylacetate and a carboxylated styrene/butadiene are used as the polymers. The aziridine can be held separate from the polymers prior to crosslinking. The composition is useful as a wood adhesive or coating composition.

  • Patent number: 5703189
    Abstract: An saturated nitrile-conjugated diene copolymer obtained by copolymerizing acrylonitrile with butadiene in the presence of a free radical initiator and an alkylthiol compound as a molecular weight modifier. A part of the monomers is incorporated in a monomer charge before polymerization, and the remainder thereof is added in a polymerization mixture during polymerization. The alkylthiol compound has 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and further has a sulfur atom directly bound to at least one of the tertiary carbon atoms. The copolymer has a Mooney viscosity of 15 to 450 and a bound nitrile content of 10 to 60% by weight. The breadth (.DELTA.AN) of compositional distribution of the unsaturated nitrile in the copolymer is 3 to 20. The copolymer is used in combination with a sulfur-containing vulcanizer.

  • Patent number: 5635556
    Abstract: A heat resistant polymer such as a styrene maleic anhydride copolymer which has been contaminated with a minor amount of a vinyl chloride polymer such as polyvinyl chloride may be stabilized sufficiently by incorporation of calcium carbonate to allow contaminated heat resistant polymer reclaimed in this manner to match the performance of non-contaminated heat resistant polymer. Instrument panels comprising such heat resistant polymers and polyvinyl chloride polymers may thus be readily recycled and reused to form new molded articles exhibiting with little or no deterioration in properties.
