Kopolymer som har strukturelle enheter avledet fra monomerer som er (A) minst en etylenisk umettet alkohol, karboksylsyre eller ester, med minst en av (B) en etylenisk umettet karboksylisk ester med en polar gruppe i esteren og (C) et etylenisk umettet karboksylisk amid. Det er også beskrevet anvendelse av en slik kopolymer t hydro- karbon- og vandige fluidmedia. This invention relates to a copolymer having structural units derived from monomers which are (A) at least one ethylenically unsaturated alcohol, carboxylic acid or ester, with at least one of (B) an ethylenically unsaturated carboxylic ester with a polar group in the ester, and (C) an ethylenically unsatured carboxylic amide. The invention also relates to the use of such a copolymer in hydrocarbon and aqueous fluid media.
