COPOLYMERS OF ETHYLENICALLY UNSATURATED CARBOXYLIC ACID ESTERS WITH POLYOXYALKYLENE ETHERS OF LOWRE, UNSATURATED ALCOHOLS AS FLOW-IMPROVING AGENTS FOR PARAFFIN-CONTAINING OILS

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.
