Patent

CA 2704432

A copolymer containing, as monomer components, a) at least one sulfonic acid-containing compound, b) at least one nitrogen-containing N-vinylamide, one acrylamide or methacrylamide and c) at least one bifunctional or higher-functional vinyl ether is proposed. These copolymers are suitable in particular as thixotropic agents, antisegregation agents and water retention agents and overall as an additive in cement-containing but also gypsum-based systems. Such copolymers having a molecular weight of > 40 000 g/mol can be used in particular as admixtures in the exploration of mineral oil and natural gas deposits.

L'invention se rapporte à un copolymère contenant comme composants monomères a) au moins un composé contenant de l'acide sulfonique, b) au moins un N-vinylamide azoté, un acrylamide ou un méthacrylamide et c) au moins un éther vinylique bifonctionnel ou polyfonctionnel. Ces copolymères sont particulièrement adaptés pour être utilisés en tant qu'agents d'accrochage, en tant qu'agents antiségrégation et en tant qu'agents rétenteurs d'eau et globalement en tant qu'additifs dans des systèmes cimentaires mais aussi dans des systèmes à base de plâtre. Ces copolymères ayant une masse moléculaire supérieure à 40 000 g/mole peuvent être notamment employés comme additifs dans le domaine de l'exploration pétrolière et gazière.
