  • Patent number: 10800927
    Abstract: The present invention provides an aqueous composition for coating substrates comprising: one or more emulsion copolymer, the emulsion copolymer being a copolymerization product of a monomer mixture comprising a monomer of formula I, wherein R1 is hydrogen or methyl, X is a divalent organic alkylene oxide group, n is an integer ranging from 1 to 50 and R2 is hydrogen or an aliphatic or aromatic hydrocarbon group having from 1 to 20 carbon atoms, and a phosphate surfactant. When incorporated into a coating composition, the coating composition show both improved stain-resistance properties and anti-clogging properties.
    Type: Grant
    Filed: December 22, 2014
    Date of Patent: October 13, 2020

  • Patent number: 10058099
    Abstract: The invention provides methods and materials for decontamination of surfaces and fabrics, such as non-woven fabrics, that are contaminated with infestations of microorganisms such as bacteria. Biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group can be used to decontaminate infested surfaces in the presence of oxygen and, optionally, illumination. Fibers incorporating biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group, wherein the oligomer is physically associated with or covalently bonded to, or both, the fiber-forming polymer can be used to form non-woven mats. Biocidal non-woven mats prepared by methods of the invention, incorporating the biocidal oligomers, can be used to suppress bacterial growth in wound and surgical dressings and personal hygiene products.
