Mary Anne Regina Matthews 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).

  • Aqueous polymer blend composition
    Patent number: 7105593
    Abstract: An aqueous polymer blend composition containing particles of a first polymer and particles of a second polymer with preferred molecular weight ranges is provided. Coatings prepared from the aqueous polymer blend composition may be employed as coatings which have water whitening resistance and provide resistance to efflorescence to cementitious substrates, such as roof tiles. A method of preparing a coated cementitious substrate with the aqueous polymer blend composition and an article containing the coated cementitious substrate are also provided.
    Type: Grant
    Filed: November 24, 2004
    Date of Patent: September 12, 2006
    Assignee: Rohm and Haas Company

  • Aqueous polymer composition
    Publication number: 20030224157
    Abstract: An aqueous polymer composition containing particles of a first polymer and particles of a second polymer with preferred molecular weight ranges, and wax is provided. Coatings prepared from the aqueous polymer composition may be employed as coatings which have water whitening resistance, bead water, and provide resistance to efflorescence to cementitious substrates, such as roof tiles. A method of preparing a coated cementitious substrate with the aqueous polymer composition and an article containing the coated cementitious substrate are also provided.
