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