A method for making a polymer includes adding a first portion of a colloidal stabilizer to an aqueous medium, adding a monomer mixture, said monomer mixture including a monomer charge and a second portion of colloidal stabilizer and said monomer charge including from about 40 parts by weight to about 70 parts by weight of a vinyl ester monomer per 100 parts by weight monomer charge and from about 30 parts by weight to about 60 parts by weight of a (C.sub.1 -C.sub.12)alkyl (meth)acrylate monomer per 100 parts by weight monomer charge, to the aqueous medium and polymerizing the monomers to form an emulsion of the polymer in the aqueous medium.
