    摘要: Nonaqueous polymer dispersions are obtainable by polymerization of esters (A) of acrylic acid and/or methacrylic acid and/or ethylacrylic acid with C.sub.1 -C.sub.20 -alcohols in an organic solvent or a mixture of organic solvents in which the polymers formed are insoluble, and in the presence of copolymers (B) having a molecular weight of from 500 to 20,000 and obtainable by bulk or solution polymerization of monoolefinically unsaturated monomers at from 180.degree. to 400.degree. C. and from 1 to 200 bar, and the said dispersions are used for the production of finishes, coating materials and adhesives.
