Abstract:
1. A polymer system comprising: A.) an anionic polymer selected from the group consisting of (i) anionic polymers comprising; (ii) graft co-polymers comprising a first moiety derived from monoethylenically unsaturated C B.) a modified polyamine polymer selected from the group consisting of (i) modified polyamines having the formulae  wherein m is an integer from 0 to about 400; n is an integer from 0 to about 400; k is less than or equal to n wherein (ii) modified polyamines having formula (I): wherein R 2 is C 2 –C 4 linear or branched alkylene, and mixtures thereof; subscript index x has a value from about 1 to about 50; at least one R 3 moiety is an anionic capping unit, with the remaining R 3 moieties being selected from the group comprising hydrogen, C 1 –C 22 alkylenearyl, an anionic capping unit, a neutral capping unit, and mixtures thereof; and mixtures thereof.
