Abstract

The present invention relates to a polymer comprising an N-vinyl amide monomer and a dual functional monomer. In the case where the dual functional monomer incorporates a glycidyl acrylate, a third polymerizable monomer is also included. The polymer can be varied in charge.

Claims (5)

1. A polymer consisting of:

a) 15-92 weight % of a N-vinyl caprolactam (VCL) monomer;

b) 1-10 weight % of a glycidyl methacrylate (GMA);

c) 5-10 weight % of a dimethylaminopropyl methacrylamide (DMAPMA) monomer; and

d) 2-7 weight % of a hydroxyethyl methacrylate (HEMA) monomer.
