Patent number: 6958380Abstract: The invention relates to improved polyurethane ionomers and methods for making the same. It was found that the polyurethane anionomers obtained by using the method of the invention had improved physical properties than those made by conventional methods. For example, the polyurethane ionomers produced by the method of the invention exhibit a plateau in the plot of elasticity modulus (as log10E?) vs. temperature over a useful and relatively broad temperature and frequency range. The polyurethane ionomers have nearly temperature-independent elasticity over a 50° C. range in the region of ˜?20 to +75° C. Another advantage is that the polyurethane ionomers of the invention are optically clearer than the conventionally prepared polyurethane ionomers. A further advantage of the invention is that the synthetic process of making the polyurethane ionomers is much faster than the known process for equivalent compositions. Additionally, striking tensile strength properties were observed for the polyurethane ionomers.Type: GrantFiled: July 1, 2002Date of Patent: October 25, 2005Assignees: Callaway Golf Company, Brown UniversityInventors: William M.

Patent number: 6646091Abstract: Coating compositions include polymeric particles, an isocyanate-containing crosslinking agent, and water. The polymeric particles include at least one incorporated monoalkenyl aromatic monomer, at least one incorporated vinyl-containing surfactant macromonomer, and at least one incorporated acrylic monomer. At least one incorporated acrylic monomer in the polymeric particles includes a hydroxyl, amine, or a carboxylic acid functional group. The crosslinking agent is an isocyanate-containing organic compound or such a compound with blocked isocyanate groups. Coating compositions may be deposited and cured by heating to form crosslinked coating compositions. Such crosslinked coating compositions exhibit excellent solvent resistance.Type: GrantFiled: February 11, 2002Date of Patent: November 11, 2003Assignee: Johnson Polymer, Inc.Inventors: James W. Taylor, Susan L. Renner
