Abstract
Latex-liopophilic polymers comprise of a lipophilic polymer and polymerized alpha, beta-ethylenically unsaturated monomer units are formed by polymerizing alpha, beta-ethylenically unsaturated monomer units in an aqueous medium containing a lipophilic polymer, an initiation catalyst, and, optionally, a graft promoting system. Typically, the latex-lipophilic polymer is a graft polymer having the lipophilic polymer as its backbone, and a plurality of the polymerized alpha, beta-ethylenically unsaturated monomer unit grafted onto the lipophilic backbone.
