  • Process for producing a stabilized latex emulsion adhesive
    Patent number: 5081166
    Abstract: An improved process for producing stabilized core-shell latex emulsion adhesives is disclosed. In a process which comprises preparing a hydrophilic polymer and thereafter contacting the hydrophilic polymer with a hydrophobic monomer for producing an inverted core-shell latex emulsion, the improvement comprises the additional step of adjusting the pH of the inverted core-shell latex emulsion for dissolving the hydrophilic polymer, thereby to produce a stabilized latex emulsion adhesive.
    Type: Grant
    Filed: November 2, 1990
    Date of Patent: January 14, 1992
    Assignee: S. C. Johnson & Son, Inc.
    Inventors: Richard A. Kiehlbauch, Vince S. Volk, Lee W. Morgan, Richard J. Esser, Dennis P. Jensen
  • Stable emulsion polymers and methods of preparing same
    Patent number: 4894397
    Abstract: An improved process for pruducing stabilized, core-shell latex emulsions is disclosed. In a process which comprises preparing a hydrophilic polymer and contacting the hydrophilic polymer with a hydrophobic monomer for producing an inverted core-shell latex emulsion, the improvement comprises the additional step of adjusting the pH of the inverted core-shell latex emulsion to dissolve the hydrophilic polymer, thereby to produce a stabilized, core-shell latex emulsion.
