Ethylene-vinyl ester copolymer emulsions

A method for making a concentrated emulsion, adaptable to use as a pour point improver and comprising (1)(a) at least one copolymer of ethylene with a vinyl ester of a C.sub.1 -C.sub.24 -carboxylic acid (polymer P1) and (b) at least one polyalkyl (meth) acrylic acid ester polymer (polymer P2);

• (2) a liquid carrier medium which does not dissolve polymers P1 and F2;
• and, additionally, as an eumulsifer, (3) a graftor block-copolymer of the formula
• AY,
• wherein A is a segment of a copolymer of ethylene with a vinyl ester of a C.sub.1 -C.sub.24 -casrboxylic acid (corresponding to polymer P1) or of a polymer of an ester of acrylic acid and/or of methacrylic acid with a C.sub.1 -C.sub.40 -alkanol, wherein Y is at least one segment formed by the polymerization of vinyl monomers which predominantly are esters of acrylic acid or methacrylic acid with a C.sub.1 -C.sub.40 -alkanol, and wherein the carrier medium is a solvent for segment Y, which method comprises dissolving said graft- or block-copolymer in said carrier medium, which swells polymers P1 and P2 to an extent of 10-300 percent, and then emulsifying polymers P1 and P2 therein at a temperature from 40.degree. C.-150? C. using shear forces.
