International ClassC08L 027/06AbstractThe 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.Other References
