Abstract

Methods describing a process for the production of polysiloxane containing masses, containing surface treated filler material, by continuously feeding materials to a screw extruder ( 12 ) in which they are mixed and conveyed to an outlet ( 14 ) with removal of gaseous materials therefrom. The screw extruder ( 12 ) has at least two screws ( 22 ) located in communicating chambers distributed radially about a common axis ( 26 ) and extending with the axis of each screw parallel to the common axis ( 26 ). The materials being mixed in the extruder typically comprise (a) a polysiloxane, (b a reinforcing filler and (c) a hydrophobing agent. Each material is fed into the extruder ( 12 ) as the material itself or in admixture with any one or more of the others of (a), (b) and (c).
