Abstract
The present invention is directed to a new aqueous dispersion of surface active polymer which demonstrates enhanced surface active and performance properties more particularly as a foaming agent. The polymer comprises a vinyl monomer having at least one quaternized nitrogen atom, a vinyl monomer having at least one amide group, a vinyl monomer bearing both a hydrophobic and a hydrophylic group and optionally, a vinyl carboxylic monomer.
