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.
Claims9
A polymer having chelating functionality consisting essentially of units derived from
- (a) an ethylenically unsaturated aminocarboxylate monomer having the following general structure:
- wherein X1, X2 and X3 are each, independently, hydrogen or a mono- or polyvalent cation and the total charge on the monomer is zero;
- and one, and only one, of R1 and R2 is an —OH group, and the other is a polymerizable arm comprising a vinyl group and derived from one or more ethylenically unsaturated monomers, wherein the polymerizable arm has one of the following structures:
- wherein R4 is hydrogen or —CH3.
