62795-194 ABSTRACT OF THE DISCLOSURE Disclosed herein is a non-aqueous dispersion of an addition polymer in an alkyd medium. The alkyd has a z-average molecular weight (Mz) of greater than about 150,000 and an NVM of less than about 70%. The addition polymer is produced by polymerizing two or more monomers in the presence of the alkyd by a radical addition polymerization. At least one of the monomers is (meth)acrylonitrile, hydroxyethyl (meth)acrylate, methyl (meth)acrylate, (meth)acrylamide, vinyl chloride, vinylidene chloride, (meth)acrylic acid, itaconic acid, maleic acid or fumaric acid. At least one of the monomers has a hydroxy-functionality. The polymerization is conducted in the presence of a chain transfer agent. The non-aqueous dispersion is particularly suitable for interior or exterior applications in the architectural industrial maintenance and traffic paint and coating industries.
