COPOLYMER BASED ON A COMPOUND COMPRISING SULFONIC ACID
The invention relates to a copolymer comprising, as monomer components, a) at least one compound comprising sulfonic acid, b) at least one N-vinylamide comprising nitrogen, an acrylamide, or methacrylamide, and c) at least one bifunctional or higher functional vinyl ether. Said copolymers are particularly suited as actuators, anti-segregation agents, and water retention agents, and altogether as additives in cementious as well as gypsum-based systems. Such copolymers having a molecular weight > 40,000 g/mol can particularly be used as additives in the exploration of petroleum and natural gas deposits.
