A non-aqueous dispersion of a polymer in a non-polar hydrocarbon. The polymer is produced by a free-radical addition polymerization reaction of a group of monomers including at least one polar monomer and at least one amine-functional monomer which takes place in the presence of an alkyd resin.

Automotive coatings from non-aqueous dispersions

A hydroxy-functional polymer having a number average molecular weight, as determined by gel permeation chromatography, of from about 1800 to about 2700 and which consists essentially of polymerized monomers of 10-40% by weight, based on the total weight of the polymer, styrene; 20-55% by weight isobornyl methacrylate; and 20-55% by weight hydroxypropyl methacrylate; where the total of the monomers equals 100% are disclosed. The polymers are especially useful in combination with polyisocyanates as clearcoats in clearcoat/basecoat coating applications.
