  • Alkylated fluorochemical oligomers and use thereof in the treatment of fibrous substrates
    Patent number: 7049379
    Abstract: This invention provides a method of treating fibrous substrates, such as leather, by contacting the substrate with a fluorochemical compound comprising: a fluorochemical oligomeric portion comprising an aliphatic backbone with a plurality of pendant fluoroaliphatic groups, each fluoroaliphatic group having a fully fluorinated terminal group and each independently linked to a carbon atom of the aliphatic backbone through an organic linking group; an aliphatic moiety; and a linking group which links the fluorochemical oligomeric portion to the aliphatic moiety. The fluorochemical compounds provide desirable oil, water and stain repellency to fibrous substrates.
    Type: Grant
    Filed: November 6, 2001
    Date of Patent: May 23, 2006
    Assignee: 3M Innovative Properties Company
    Inventors: Chetan P. Jariwala, James D. Eggleston, Michael A. Yandrasits, Rudolf Dams, Dirk M. Coppens
