Abstract: The invention relates to graft polymers comprising from 20 to 99.9% by weight of an ethylene copolymer (base polymer) and from 0.1 to 80% by weight of a graft component. The base polymer contains from 30 to 95% by weight of ethylene and from 5 to 70% by weight of vinyl esters of saturated, aliphatic C2- to C18-monocarboxylic acids or from 4 to 50% by weight of vinyl esters of saturated, aliphatic C2- to C18-monocarboxylic acids and from 1 to 20% by weight of linear or branched C3- to C18-monoolefins. Graft components are N-substituted alpha,beta-unsaturated dicarboximides and/or dicarboxamides and/or dicarboxylic acid monoamides and/or ammonium salts of the monoamides. The graft polymers are used to improve the flow properties of paraffin-containing mineral oils and mineral oil distillates.

Abstract: The invention relates to novel copolymers made from ethylenically unsaturated carboxylic acid esters with polyoxyalkylene ethers of lower, unsaturated alcohols, to their preparation, to their use as flow improvers (flow assistants) for paraffin-containing oils, and to oils which contain such copolymers. The invention also relates to the use of known copolymers made from ethylenically unsaturated carboxylic acid esters with polyoxyalkylene ethers of allyl and/or methallyl alcohol as flow improvers for paraffin-containing oils.
