Abstract:
An organic particulate-filled adhesive comprising ionomeric particulates dispersed in a polymer matrix further comprising water-soluble polymer, the ionomeric particulate comprising:(a) at least one vinyl monomer selected from the group consisting of acrylic acid ester of non-tertiary alcohol having 1 to 14 carbon atoms, vinyl acetate, styrene, octylacrylamide, and N-vinyl lactams; (b) at least one acid monomer containing, a carboxylic acid; (c) at least one metal oxide, and (d) at least a first and a second surfactant, the first being a monomer surfactant that aids in the initial formation of the ionomeric particulate and at least a portion of the monomer surfactant polymerizes to become a part of the ionomeric particulate.
