Blanche H. Black 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).

  • Starch polymer graft composition and method of preparation
    Patent number: 5116927
    Abstract: Monomers such as hydrophobic olefinically unsaturated monomers have been grafted onto maltodextrins and other low molecular weight starch hydrolyzates to prepare stable fluid emulsions of coatable viscosity and reduced graininess. Polymer films of high tensile strength which are useful in a variety of applications, including high temperature applications may be formed by casting and drying these emulsions.
    Type: Grant
    Filed: June 10, 1991
    Date of Patent: May 26, 1992
    Assignee: Sequa Chemicals, Inc.
    Inventors: William C. Floyd, Louis R. Dragner, Blanche H. Black, Bernard F. North

  • Starch based binder composition for non-woven fibers or fabrics
    Patent number: 5026746
    Abstract: A binder for non-woven fibers or fabrics is prepared comprising a starch-polymer graft, starch and a starch crosslinking agent. An acrylamide copolymer may optionally be included. The binder is useful for non-woven fibers such as a polyester fiber mat, and particularly single ply, bitumin roofing materials.
