Abstract
A method for producing a stabilizer composition for a polymer, particularly a polymer containing halogen such as polyvinyl chloride, in which components for forming the stabilizer composition are mixed in an extruder and continuously discharged therefrom, in which an impact modifier is admixed. A correspondingly produced stabilizer composition and the use of a planetary roller extruder to produce a stabilizer composition.
Claims16
A method for producing a stabilizer composition for a polymer, in particular a polymer containing halogen such as polyvinyl chloride, wherein components for forming the stabilizer composition are mixed in an extruder and continuously discharged therefrom, and wherein an impact modifier is admixed, wherein a planetary roller extruder is used as extruder and the extrusion is carried out with downstream decreasing shear forces.
(canceled)
A method using a planetary roller extruder for producing a stabilizer composition, wherein shear forces are adjusted via a different number of planetary spindles in modules of the planetary roller extruder.
