Thomas Lawrence Pytlewski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Washing composition and use of polymer to clean and provide soil resistance to an article
    Patent number: 5843192
    Abstract: The present invention provides a composition useful in a washing process containing at least one vinyl amide polymer. The vinyl amide polymer contains from 5 to 100 weight percent of at least one vinyl amide monomer, and from 0 to 95 weight percent of one or more vinyl ester monomers. The present invention also provides a method of cleaning an article and a method of providing soil resistance to an article using the vinyl amide polymer.
    Type: Grant

    Date of Patent: December 1, 1998
    Assignee: Rohm and Haas Company
    Inventors: Thomas Cleveland Kirk, Curtis Schwartz, Richard James Tallent, Thomas Lawrence Pytlewski
  • Fabric washing composition and method for inhibiting deposition of dye
    Patent number: 5730760
    Abstract: The present invention provides a fabric washing composition and aqueous treatment solution for inhibiting dye from transferring from one fabric to the same or different fabric in a fabric washing process. The fabric washing composition and aqueous treatment solution contain at least one dye deposition inhibiting polymer. The dye deposition inhibiting polymer contains, as polymerized units, from 5 to 100 weight percent of at least one vinyl amide monomer and from 0 to 95 weight percent of one or more vinyl ester monomers. The present invention also provides a method for inhibiting the deposition of dye by adding at least one of dye deposition inhibiting polymer useful in the present invention to a fabric washing process where dye may be released.
