Abstract
A process of manufacturing a poly(dimethylaminoethyl(meth)acrylate) comprising polymerizing dimethylaminoethyl(meth)acrylate in water and in the presence of sufficient acid to form a solution having a pH of less than 6. The polymer is made in an aqueous medium and with a free radical initiator. The polymer is useful as a foam booster in a variety of formulations and applications.
