Abstract
A method of preparing a dispersion of polymeric particles is disclosed. Monomers are emulsion polymerized in the presence of an ionic monomer to produce highly charged polymeric particles. At least 50% of the ionic monomer in the dispersion is bound to the polymeric particles.
Claims20
A method of preparing a dispersion of monodispersed polymeric particles comprising:
- dispersing monomers in an emulsion containing an ionic monomer;
- and
- polymerizing the monomers to produce monodispersed polymeric particles wherein at least 50% of the ionic monomer in the dispersion is bound to the polymeric particles.
A dispersion of monodispersed polymeric particles having an ionic monomer bound thereto, said ionic monomer comprising sodium styrene sulfonate.
