COPOLYMERS WITH GEM ACETOPHOSPHONATE GROUPS

摘要

the present invention, the carboxyl groups and polyoxyethylene Al comprises an chelates, and copolymers containing the instrumental and the main hydrocarbon chain, characterized in that further comprising a gem acetonitrile phosphonate, the air adjuvants for the suspension of mineral particles including the polymer, and to a method for producing the copolymer. Finally, also relates to, the use of said copolymers for reducing the sensitivity of, and hydraulic binder for the clay and the alkali metal sulfates and fluidized to maintain the fluidity of the suspension of the mineral particles. Finally, a composition of mineral particles comprising such copolymers.
