The invention provides polymers comprising repeating units derived from at least one monomer comprising at least one functionalized or unfunctionalized acryloyl moiety and at least one lactam moiety; at least one monomer comprising at least one sulfonic acid moiety or a salt thereof; and at least one crosslinker. The invention further provides various compositions comprising the polymers. The invention furthermore provides applications of these compositions in various industrial arts, particularly in oilfield operations such as drilling and cementing. L'invention concerne des polymères comprenant des motifs répétés dérivés d'au moins un monomère comprenant au moins un groupement acryloyle fonctionnalisé ou non fonctionnalisé, et au moins un groupement lactame ; au moins un monomère comprenant au moins un groupement acide sulfonique ou un sel de celui-ci ; et au moins un agent de réticulation. L'invention concerne également diverses compositions comprenant les polymères. L'invention concerne en outre des applications de ces compositions dans différents domaines industriels, notamment dans des opérations sur champ pétrolifère, telles que le forage et la cimentation.
