  • Fixation of multivalent metal salts of carboxyl-containing vinyl monomers on fibrous substrates
    Patent number: 4072784
    Abstract: Water-soluble multivalent metal salts of carboxyl-containing vinyl monomers are polymerized in situ in fibrous substrates and fixed therein as network polymeric structures. This finish is useful for development of flame retardance, sanitizing characteristics, and other special performance qualities in fibrous compositions and fabrics.
    Type: Grant
    Filed: April 9, 1976
    Date of Patent: February 7, 1978
    Assignee: The United States of America as represented by the Secretary of Agriculture
    Inventors: Vidabelle O. Cirino, Stanley P. Rowland
  • Method of polymerizing and fixing carboxyl-containing vinyl monomers in high conversion on fibrous substrates
    Patent number: 3995998
    Abstract: A fibrous material consisting of cellulosic or other natural fiber, synthetic fibers, or blends of various fibers is treated with an aqueous reagent system having a pH above 3.6 that is comprised of one or more carboxyl-containing vinyl monomers, a free-radical initiator, and a suitable base to adjust the pH. Comonomers and water-soluble di- or polyfunctional vinyl monomers may be included. Polymerization is conducted at elevated temperature in an atmosphere in which air may be diluted by steam and/or steam-nitrogen. The polymer is durably fixed to the fibrous substrate and contributes various special performance properties thereto.
