ABSTRACT:
A process for preparing a rubber modified thermoplastic resin, in which a latex in aqueous emulsion is prepared in the presence of an ionic surfactant; a vinyl monomer insoluble or substantially insoluble in water is added, and the particles of the latex are transferred to the monomer to form an organic phase using a transfer agent of opposite charge to the surfactant; and a polymerization of the organic phase is performed.
