Process for the production of thermoplastic moulding compounds

A process for the production of acrylonitrile-butadiene-styrene (ABS), wherein

• at least a first reagent (11) that contains or consists of styrene-acrylonitrile copolymer (SAN) and
• a second reagent (12) that contains or consists of rubber, in particular in the form of SAN grafted elastomer
• of the thermoplastic moulding compounds are fed to a loop conduit (29) which comprises at least one static mixer (36), wherein
• at least one solvent is added to the reagents (11, 12), wherein
• the reagents (11, 12) and the at least one solvent are first mixed to form a premix, and the premix is fed to the loop conduit (29), wherein
• the reagents (11, 12) are pressed in loops through the loop conduit (29) and passing the static mixer (36), whereby the reagents (11, 12) are dispersed to form a dispersion (15) in the static mixer (36), and wherein
• the premix is pressed through the static mixer (36) back to a mixing vessel (50), in which the premix has been formed.
