Abstract
Coating compositions comprising hydroxy functional film formers and a novel flow control additive comprising a stable crosslinked dispersion prepared by addition polymerization of (a) first and second ethylenically unsaturated monomers each bearing functionality capable of crosslinking with the other and (b) at least one other monoethylenically unsaturated monomer, in the presence of (I) organic liquid which is a solvent for the polymerizable monomers, but a non-solvent for the resultant polymer and (II) a novel polymeric dispersion stabilizer. The stabilizer bears pendent ethylenic unsaturation capable of reacting with monomers employed in the addition polymerization and comprises a random copolymer segment of ethylenically unsaturated monomers, some of which are characterized in that homopolymers thereof would be substantially insoluble in the organic liquid used to form the stable dispersion and some of which are characterized in that homopolymers thereof would be substantially soluble in the organic liquid used to form the stable dispersion.
