COPOLIMERS, OILS CONTAINING PARAFFIN, PROCESS FOR THE PREPARATION AND APPLICATION OF THE MENTIONS COPOLIMEROS, COMPOSICOS CONTAINING ONE OF THE MENTIONS OF THE COPOLIMERS AND APPLICATION OF THE MENTIONS COMPOSITIONS

摘要

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.
