Abstract

A process for the continuous preparation of impact-modified thermoplastic molding compositions which comprise an elastomeric soft phase in disperse distribution in a vinylaromatic hard matrix, where in a first reaction zone the rubber required to form the soft phase is polymerized anionically in solution, substantially without backmixing, to complete conversion, the rubber is supplied, directly or following the addition of a terminator or coupling agent, to a second reaction zone in which, with the addition of an amount of vinylaromatic monomer sufficient for phase inversion and of further anionic initiator, polymerization is carried out until phase inversion is obtained, and in a third reaction zone the polymerization is continued to its end anionically with the amount of vinylaromatic monomer required to form the impact-modified thermoplastic molding composition.
