  • Patent number: 8362149
    Abstract: The invention provides a golf ball material composed of an ionomeric resin composition obtained by melt-blending under applied heat one or more compounds selected from among UV/EB-curable materials with, in the presence of a peroxide, a non-ionomeric thermoplastic resin and an ionomeric resin; or of an ionomeric resin composition obtained by using, instead of the ionomeric resin, an acid-containing polymer base of the ionomeric resin and subjecting the acid-containing polymer composition similarly prepared by melt-blending under applied heat to an acid-neutralizing reaction with a metal ionic species. Methods for preparing such a material, and golf balls which include as a component therein a molding made of the golf ball material are also provided. The golf ball material has a good thermal stability, flow and processability, and can thus be used to obtain high-performance golf balls endowed with an excellent abrasion resistance, scuff resistance, durability and flexibility without a loss of rebound.

  • Patent number: 6140421
    Abstract: The specification discloses a method for the manufacture of a fluorescent polyphenolic product with high UV absorbance, its subsequent epoxidation as well as polyphenolic products and epoxidized derivatives and compositions thereof. The polyphenolic products are prepared by heating glyoxal at a temperature of about 80.degree. C. to about 100.degree. C. with a molar excess of a phenol in the presence of an acidic catalyst which is eliminated from the reaction mixture at a temperature below about 170.degree. C. The total mole ratio of glyoxal to phenol charged to the reaction mixture is about 0.15 to 0.22 moles of glyoxal for each mole of phenol. The glyoxal is added continuously or by stepwise additions to the phenol so as to keep the aldehyde units in the reaction mixture to less than about 70% of the aldehyde units in the total quantity of glyoxal to be charged for making the polyphenol. Water is distilled stepwise or continuously from the reaction mixture.

  • Patent number: 6140391
    Abstract: The present invention provides a jet ink composition suitable for application onto a substrate comprising an ink carrier, a colorant, a polyol, an aldehyde-based cross-linking agent, and a catalyst that promotes a reaction between the cross-linking agent, the polyol, and the substrate. The present invention further provides a process of jet ink printing onto a substrate comprising projecting a stream of ink droplets to said substrate, controlling the direction of the droplets so that the droplets form the desired printed image on the substrate, and heating the image to obtain a cured printed image. Examples of preferred cross-linking agents are modified melamine formaldehyde resin and modified urea formaldehyde resin. The substrates preferably possess carboxyl, hydroxyl, amide, or sulfhydryl groups. An example of a preferred substrate is cellulose. The cross-linking reaction is carried out at relatively moderate temperatures and at high speeds.
