ABSTRACT:
An emulsion polymer of a water insoluble vinylic monomer and an acrylic monomer is formed by precharging a portion of the acrylic monomer and thereafter adding a comonomer charge corresponding to the final desired composition of the vinylic monomer and acrylic monomer at an addition rate generally corresponding to the steady state monomers concentration. A high non-volatiles content is maintained to inhibit the acrylic monomer from partitioning into the aqueous phase.
