Patent number: 8338558Abstract: Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material.Type: GrantFiled: June 1, 2006Date of Patent: December 25, 2012Assignee: Lubrizol Advanced Materials, Inc.Inventors: Stuart N. Richards, Andrew J. Shooter

Patent number: 8288485Abstract: Disclosed are anhydrous transparent dispersions of polyurethane(meth)acrylate particles in a reactive diluent, which can be obtained by reacting a polyisocyanate with at least one polyol and a nucleophilically functionalized (meth)acrylic acid ester in the reactive diluent. The inventive dispersions are characterized in that the polyurethane(meth)acrylate particles have an average diamert of less than 40 nm. The invention further relates to a method for producing such dispersions, the use thereof as an adhesive, cut glass, or impact resistance modifier, and a molded article made from said dispersion.Type: GrantFiled: July 14, 2006Date of Patent: October 16, 2012Assignee: Dritte Patentportfolio Betelligungsgesellschaft mbH & Co. KGInventors: Klaus-Uwe Koch, Daniele Rutz

Patent number: 8288478Abstract: Golf balls containing at least one layer made from a thermoplastic polyurethane or polyurethane-urea that is the reaction product of a polyisocyanate with moisture-resistant polyol and a curing agent are provided. The moisture-resistant polyol may be prepared by dimerizing unsaturated aliphatic monocarboxylic acid or ester containing 10 to 60 carbon atoms followed by reacting it with a monomeric, oligomeric, or polymeric diol. In one preferred version, the moisture-resistant polyol is a branched polyester polyol containing 36 carbon atoms. The composition can be prepared using prepolymer or one-shot manufacturing techniques. The resulting golf ball has desirable playing performance properties including high resiliency, toughness, impact durability, moisture-resistance, and soft feel.Type: GrantFiled: February 25, 2010Date of Patent: October 16, 2012Assignee: Acushnet CompanyInventors: Murali Rajagopalan, Derek A. Ladd, Michael J. Sullivan
