Normally tacky, pressure sensitive adhesive compositions comprise one or more polymers containing pendant functional groups attached to a polymer backbone and having the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano, and wherein said polymer is selected from the group consisting of

Methods of using pressure-sensitive adhesives

The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises a film former and polymeric composition. The polymeric composition comprises about 30 to about 50 weight percent of a substantially non-self-polymerizable monomer and about 50 to about 70 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The polymeric composition and film former are substantially inseparable by chromatographic means.

Latex-paints

Latex paints

The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises, in part, a supplemental polymer. The supplemental polymer comprises about 20 to about 60 weight percent of a substantially non-self-polymerizable monomer and about 40 to about 80 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The supplemental polymer and binder are substantially inseparable by chromatographic means.

ICI viscosity of a paint is improved by incorporating into the paint an acrylic polymer emulsion or latex made with the use of a water soluble chain transfer agent, preferably one that comprises both sulfur functionality and hydroxyl functionality. A preferred chain transfer agent is monothioglycerol.

Emulsion polymers and paint formulated therewith

Polyamines having at least two amine groups are incorporated into a polymer system comprising an anionic surfactant and a polymer having at least one anionic pendant group. The resulting polymer system typically exhibits at least one improved physical property.
