COPOLYMÈRES À GROUPEMENTS GEM-ACÉTOPHOSPHONÉS
The invention relates to a copolymer comprising a main hydrocarbon chain and side groups including carboxylic groups, polyoxyalkylate groups, and gem acetophosphonate groups, an adjuvant for suspensions of mineral particles comprising said copolymer and a method for preparing said copolymer. Finally it also relates to the use of said copolymer for fluidifying and maintaining fluidity of suspensions of mineral particles and for reducing the sensitivity of hydraulic binders to clays and alkali metal sulfates. Finally it relates to a composition of mineral particles comprising this copolymer.
