Abstract
The present invention provides novel polymers having chelating functionality and comprising units derived from an ethylenically unsaturated aminocarboxylate monmomer which comprises units derived from ethylenediamino disuccinic acid or its salt and a polymerizable ethylenically unsaturated monomer. The polymerizable ethylenically unsaturated monomer may be selected from divinylbenzene monoepoxide, allylglicidyl ether, and glycidyl(meth)acrylate. The polymer may also comprise units derived from one or more ethylenically unsaturated monomers.
