Abstract: Highly concentrated carbon black-thermoplastic synthetic resin concentrates are prepared by adding the carbon black to the synthetic resin in at least two places in series employing a conveying apparatus which is a continuously operating screw kneader.

Abstract: 1468853 Carbon black-filled thermoplastics DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 12 June 1974 [29 June 1973] 26031/74 Heading C3P Carbon black is incorporated in a thermoplastics material by a process which comprises adding the carbon black to the thermoplastics material in a continuous screw extruder at at least two points lying one behind the other in the delivery direction. Plastics material and part of the carbon black may be introduced together at a first inlet, and the distance between inlets may be 2 to 6, preferably 3 to 5 times the diameter of the kneader screw. The process may be used to produce concentrates which may be diluted with further plastics material. Examples describe the preparation of compositions of carbon black with (1 to 4) polyethylene, (2) polypropylene and (3) polystyrene.
