Abstract

A method for producing a thermoplastic moulding compound by means of an extruder (), which comprises at least one feed zone (), at least one mixing section (), at least one venting section () and at least one discharge zone (), wherein in the at least one feed zone () a water-containing first component and a second component are supplied, in the at least one mixing section () the thermoplastic moulding compound is mixed and contained water is evaporated, in the at least one venting section () water vapour is removed from the moulding compound and in the at least one discharge zone () the moulding compound is discharged. At least one of the mixing housings () is kept at a temperature that is equal to or lower than the temperature of the moulding compound within the mixing section ().
