A method for producing a thermoplastic moulding compound by means of an extruder ( 10 ), which comprises at least one feed zone ( 20 ), at least one mixing section ( 30 ), at least one venting section ( 40 ) and at least one discharge zone ( 50 ), wherein in the at least one feed zone ( 20 ) a water-containing first component and a second component are supplied, in the at least one mixing section ( 30 ) the thermoplastic moulding compound is mixed and contained water is evaporated, in the at least one venting section ( 40 ) water vapour is removed from the moulding compound and in the at least one discharge zone ( 50 ) the moulding compound is discharged. At least one of the mixing housings ( 31, 32 ) is kept at a temperature that is equal to or lower than the temperature of the moulding compound within the mixing section ( 30 ). |
