Abstract: A process for the preparation of filler-containing thermoplastic moulding compositions by mixing fillers with thermoplastics in the melt, where a) the fillers are mixed in a mixing device in the melt with a low-molecular-weight thermoplastic having a maximum melt viscosity of 30 Pas (measured at a temperature of 20 DEG C above the melting point of the thermoplastic and at a shear gradient of 1 000 s ), b) the resultant product is discharged from the mixing device, cooled and comminuted, and c) the comminuted product in the solid phase is subsequently subjected to post-condensation.
