The process in accordance with one aspect of the invention is a continuous process that includes introducing primary raw materials comprising a non-thermoplastic elastomer into a planetary roller extruder, introducing a heat-activatable crosslinker into the planetary roller extruder for mixing with the primary raw materials, and compounding the primary raw materials and the heat activatable crosslinker to form an adhesive composition while maintaining the temperature of the adhesive composition between about 25° C. and about 100° C. The non-thermoplastic elastomer is masticated during compounding and at least some of the heat-activatable crosslinker remains generally unactivated and is available for later activation.Type: GrantFiled: December 27, 2011Date of Patent: October 8, 2013Assignee: Intertape Polymer Corp.Inventors: John Kinch Tynan, Jr., Richard Walter St. Coeur, David Michael Kovach, Thomas Lombardo

Patent number: 8529681Abstract: This invention relates to methods for chemically grafting and attaching ceragenin molecules to polymer substrates; methods for synthesizing ceragenin-containing copolymers; methods for making ceragenin-modified water treatment membranes and spacers; and methods of treating contaminated water using ceragenin-modified treatment membranes and spacers. Ceragenins are synthetically produced antimicrobial peptide mimics that display broad-spectrum bactericidal activity. Alkene-functionalized ceragenins (e.g., acrylamide-functionalized ceragenins) can be attached to polyamide reverse osmosis membranes using amine-linking, amide-linking, UV-grafting, or silane-coating methods. In addition, silane-functionalized ceragenins can be directly attached to polymer surfaces that have free hydroxyls.Type: GrantFiled: January 7, 2011Date of Patent: September 10, 2013Assignee: Sandia CorporationInventors: Michael Hibbs, Susan J. Altman, Howland D. T. Jones, Paul B. Savage
