Abstract
The present invention provides novel polymerizable monomers having chelating functionality and processes to make them. In particular, the novel monomers are ethylenically unsaturated aminocarboxylates and are prepared by reacting ethylenediamine triacetic acid or its salt with an ethylenically unsaturated monomer. The ethyleneically unsaturated monomer may be a polymerizable vinyl monomer selected from (o-, p-, m-)DVBMO, allyl glycidyl ether, and glycidyl (meth)acrylate.
