US 6,635,704 B2 · Organic particulate-filled adhesive

Abstract

An organic particulate-filled adhesive is provided comprising ionomeric particulate dispersed in a polymer matrix containing water-soluble polymer or water-dispersible polymer. The adhesive preferably contains a plasticizer. If desired, in some formulations, the adhesive can contain additives, such as opacifying agents, skin cleansers, skin moisturizers, vitamins, and herbal extracts. The adhesive can have pressure sensitive adhesive properties, although such properties are not necessary. The adhesive can be formulated so as to be useful as a repulpable adhesive and as a cosmetic adhesive.

Dependent claims

An organic particulate-filled adhesive comprising ionomeric particulates dispersed in a polymer matrix further comprising water-soluble polymer, the ionomeric particulate comprising the reaction product of:

(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;
(d) at least a first and a second surfactant, the first surfactant being a monomer surfactant that aids in the initial formation of the ionomeric particulate and at least a portion of the first surfactant polymerizes to become a part of the ionomeric particulate;
and
(e) at least one initiator.
