Abstract
A copolymer includes a main hydrocarbon chain and side groups including carboxylic groups and polyoxyalkylate groups. The copolymer further includes gem-bisphosphonate groups. A composition, such as n admixture for suspensions of mineral particles, includes the copolymer. The copolymer can be used for fluidifying suspensions of mineral particles and maintaining the fluidity of such suspensions. The copolymer can also be used for reducing the sensitivity of hydraulic compositions to clays and alkaline sulfates.
