  • Reinforced films made from water soluble polymers
    Patent number: 5667885
    Abstract: A dried film reinforced with coalescable water insoluble polymer particles which are substantially noncoalesced is disclosed. Also disclosed are dried films reinforced with noncoalesced water insoluble polymer particles which are readily water dispersible. Also disclosed are stable aqueous dispersions for formation of such films which comprise (a) a water insoluble component comprising coalescable polymer particles which have a T.sub.g less than 55.degree. C. and a majority of which have a particle size of less than 1 micron; and (b) a water soluble component which comprises a water soluble polymer capable of inhibiting coalescence of the polymer particles, or a water soluble polymer and a component capable of inhibiting coalescence of the polymer particles.
    Type: Grant
    Filed: May 14, 1996
    Date of Patent: September 16, 1997
    Assignee: Penford Products Company
    Inventors: Charles C. Nguyen, Verne J. Martin, Edward P. Pauley, Henry L. Buccigross, Stephen Rudolph
