Beschreibung
Zusammenfassung:	Aminophosphonate-containing polymers of the formula: &lsqbstr& B &rsqbstr& @ &lsqbstr& A &rsqbstr& @ wherein A represents repeating units from one or more ethylenically unsaturated comonomers; B is wherein R is hydrogen or methyl, X is hydrogen or an alkali metal, Z is CH2 - P(O)(OX)2 or C1 - C6 alkyl, aryl, cyclohexyl or alkaryl; and m and n are positive integers, m/n = 0.01 to 0.5. The novel polymers of the present invention may be used as dispersants for concentrated aqueous particulate slurries, and as corrosion inhibitors and scale inhibitors in water treatment.
