Abstract: This invention relates to a stable dispersion of a synthetic polymer in an oil medium for paints or sealants, which comprises (A) an oil medium capable of dissolving a monomer but incapable of dissolving a polymer formed from the monomer and (B) a polymer component obtained by block- or graft-copolymerization of a part of the oil medium (A) with a monomer copolymerizable with the oil medium (A), the weight ratio of component (A)/component (B) being from 25/75 to 95/5, and the invention also relates to a process for the preparation of such polymer dispersion.

Abstract: A thermosetting synthetic polymer dispersion obtained by copolymerizing unsaturated monomers in a non-polar organic liquid or an organic liquid having a low polarity in the presence of a stabilizer formed by reacting (1) a partially blocked isocyanate containing a free isocyanate group and a blocked isocyanate group with (2) an active hydrogen-containing, polymer compound in such a ratio that the amount of the active hydrogen group of the compound (2) is at least equivalent to the amount of the free isocyanate group of the isocyanate compound (1), and a process for the preparation of such a thermosetting synthetic polymer dispersion.
