The invention relates to a method for homogenously incorporating filler into a self-adhesive compound, in particular a thermally crosslinkable self-adhesive compound, based on non-thermoplastic elastomer in a continuously working unit with a filling part and a compounding part. The self-adhesive compound contains at least one solid component, at least one liquid component, and at least one filler, and the method has the following steps: (a) feeding at least part of the at least one solid component, such as the non-thermoplastic elastomer in particular, and optionally part of the at least one liquid component to the filling part; (b) transferring the components of step (a) from the filling part to the compounding part; (c) optionally adding additional solid components or additional parts of the solid components to the compounding part; (d) adding the at least one liquid component to the compounding part if the liquid component was not already added to the filling part in step (a); (e) producing a homogenous self-adhesive compound in the compounding part; and (f) discharging the self-adhesive compound. The invention is characterized in that at least part of the at least one filler is pre-dispersed into at least one dispersion liquid in a separate unit and the dispersion obtained in this manner is added to the compounding part. The method prevents high sheering or frictional energies while introducing the filler into the compounding part of the continuously working unit and thus allows the use of temperature-sensitive components, such as temperature-sensitive chemical crosslinking agents in particular.

A method for producing thermally crosslinkable polymers in a planetary roller extruder is presented. The planetary roller extruder has a filling part and a compounding part made of a roller cylinder region that comprises at least two, preferably at least three coupled roller cylinders, planetary spindles of which are driven by a common central spindle. The polymers are supplied in a plasticized state. The filling part is supplied with a vacuum. The flow temperatures of the central spindle and the at least two roller cylinders under a vacuum are set such that the polymers to be degassed remain in the plasticized state. One or more liquids, such as thermal crosslinkers, crosslinking accelerators, dye solutions, or dye dispersions, are metered to the plasticized polymers downstream of the vacuum degassing, preferably in a continuous manner. Finally, the resulting mixture is directly supplied to a coating assembly.
