Abstract
Novel polymeric compositions are disclosed. The polymeric compositions, in particular, are either soluble or readily dispersible in water. Such polymeric compositions can be characterized as polymeric blends containing at least one acid-functional vinyl polymer and at least one amino-functional siloxane polymer. The novel polymeric blends further include volatile aqueous media comprising water and base in an amount that is effective for preventing the acid-functional moieties of the vinyl polymer from chemically reacting with the amino-functional moieties of the siloxane polymer. Such compositions or 'blends', in general, comprise 60-99.9 parts-by-weight of the acid-functional vinyl polymer and 0.1-40 parts-by-weight of the amino-functional siloxane polymer, based upon total weight of the blended polymeric composition. Also disclosed are methods of producing the blended polymeric composition. The blended polymeric compositions are able to provide various substrates with surface coatings that are characterized as quasi-crosslinked, alkali-soluble polymeric networks exhibiting enhanced surface properties.
