ABSTRACT:
A process for the emulsion polymerization of graft copolymers comprising the steps of: a) obtaining an unsaturated polymer containing terminal or pendant polymerizable functionalities; b) dissolving the resultant unsaturated polymer in an ethylenically unsaturated monomer in the presence of a surfactant in water to form an aqueous phase; c) microfluidizing the aqueous phase of (b) to a size of less than 0.5 u; and d) subsequently graft polymerizing a monomer with the unsaturated polymer in the microfluidized aqueous phase using free radical polymerization techniques; such that the graft polymerization reaction occurs within each micelle thereby resulting in uniform particles of the predetermined particle size.
