  • Composition and method for preparing leather
    Patent number: 7637961
    Abstract: An oligomeric composition containing oligomers and at least one stabilizing component is provided. An aqueous dispersion composition containing the oligomeric composition is useful for treating tanned leather to provide leather with increased softness or strength. Also provided are a method of treating tanned leather using the composition and an article containing the treated leather.
    Type: Grant
    Filed: February 21, 2003
    Date of Patent: December 29, 2009
    Assignee: Rohm and Haas Company
    Inventors: Anton Georges El A'mma, Shang-Jaw Chiou, Robert Francis Dougherty
  • Coating and coating composition
    Patent number: 6939922
    Abstract: Provided are improved coatings, polymeric dispersions, and polymeric composites, which include crosslinked polymeric nanoparticles (hereafter “PNPs”). Also provided are methods for forming improved coatings, polymeric dispersions, and polymeric composites, which include PNPs. The PNPs have polymerized units of at least one multi-ethylenically-unsaturated monomer have a mean diameter of from 1 to 50 nanometers. PNPs having polymerized units of at least one multi-ethylenically-unsaturated monomer and at least one surface-active monomer are also provided.

  • Preparation of an aqueous composition for treating leather
    Patent number: 6663676
    Abstract: A method of preparing an aqueous composition for treating leather comprises adding a predetermined amount of a solid particulate leather treatment composition directly into a predetermined amount of water in a vessel at a tannery; and dissolving or dispersing said solid particulate composition in said water. The solid particulate composition comprises 0.1 wt % or more based on the total weight of said particulate composition of a particulate hygroscopic material. The solid particulate composition is non-dusting in humid atmospheres.
