Abstract
The present invention provides novel polymers having chelating functionality and comprising units derived from an ethylenically unsaturated aminocarboxylate monomer which comprises units derived from ethylenediamine triacetic acid or its salt and a polymerizable vinyl monomer. The polymerizable vinyl monomer may be selected from (0-, m-, p-)DVBMO, allyl glycidyl ether, and glycidyl (meth)acrylate. The polymer may also comprise units derived from one or more ethylenically unsaturated monomers.
