ETHYLENICALLY UNSATURATED MONOMERS HAVING CHELATING FUNCTIONALITY

摘要

The present invention provides novel polymerizable monomers having chelating functionality and processes to make them. In particular, the novel monomers are vinyl aminocarboxylates and are prepared by reacting iminodiacetic acid, iminodisuccinic acid, or a salt thereof and a vinyl epoxy benzene monomer.

1. An ethylenically unsaturated aminocarboxylate monomer having one or more of the following structures: wherein R1 is COOX1, R2 is COOX2, R4 is COOX4 and R5 is COOX5; X1, X2, X3, X4, X5, are each, independently, hydrogen or a mono- or polyvalent cation and the total charge on the monomer is zero; and R3 is a polymerizable ethylenically unsaturated group located at the ortho-, para-, or meta- substituted position of the benzene ring.
