Abstract
The present invention relates to a mixing apparatus at least composed of a screw-based machine Sand a screw-based machine S, where Shas heating equipment, at least in the plasticizing and homogenizing zone, and where the outlet from Shas been connected to the screw-containing barrel of S, within the plasticizing or homogenizing zone of S, a substantive feature of which is that the connection between Sand Sis brought about by a connector which has cooling equipment effective as far as the inner wall of the screw-containing barrel of S, and to a process for preparing thermoplastically processable molding compositions, in particular additive masterbatches, from at least one thermoplastic component Cand at least one component C, where the melting point or decomposition temperature Tof Cis lower, by at least about 50° C., than the temperature T, which is the lower limit of the thermoforming range of C, and where most of Cis melted only after contact with C
