ABSTRACT:
A method of producing an emulsion polymer which comprises adding a polymerizable monomer to an emulsion polymer containing a high-molecular-weight compound having a weight average molecular weight of 20,000 to 2,000,000 as a seed polymer, the amount of the unsaturated monomer being 1.5 to 9.5 times the total volume of the solids in the emulsion polymer, and thereafter, polymerizing the monomer in the presence of a film-forming aid.
