    摘要： The invention relates to an aqueous polymer dispersion comprising an anionic water-soluble dispersion polymer comprising in polymerized form a monomer mixture comprising (i) one or more anionic monomers, (ii) a first non-ionic vinyl monomer which is acrylamide, and (iii) at least one second non-ionic vinyl monomer; a water-soluble salt and a stabilizer, wherein the water soluble salt is present in an amount of at least 2.0% by weight, based on the total weight of the dispersion. The invention further relates to a process for producing the aqueous polymer dispersion, use of the aqueous polymer dispersion as a flocculating agent in papermaking or for water purification, and a process for producing paper which comprises adding one or more drainage and retention aids comprising the aqueous polymer dispersion to an aqueous suspension containing cellulosic fibers and then dewatering the obtained suspension.
