摘要：
Polymer blends contain a) from 10 to 90% by weight of an imide of a copolymer based on an .alpha.-olefin and on an ethylenically unsaturated dicarboxylic acid and a polyamine and b) from 10 to 90% by weight of a copolymer which differs from a) and contains at least two monomers selected from the group consisting of ethylene, acrylates, vinyl esters, vinyl ethers and ethylenically unsaturated dicarboxylic acids or dicarboxylic acid derivatives, and are used as additives for mineral oil middle distillates.
