Abstract
A process for preparing a rubber modified thermoplastic resin, in which a latex in aqueous emulsion is prepared in the presence of a non-ionic surfactant; a vinyl monomer insoluble or substantially insoluble water is added, and the particles of the latex are transferred to the monomer to form an organic phase using a polymer or copolymer based on carboxylic acid units capable of forming an interpolymeric complex with the non-ionic surfactant; and a suspension or bulk polymerization of the organic phase is performed.
