Process for producing mouldable polymer blends from electrically conductive organic polymers and/or organic conductors, apparatus for performing the process and the use of the polymer blends

Abstract From the Canadian patent

Substantially monomer-free, electrically conductive organic polymers and/or organic conductors are dissolved or dispersed in a melt or solution of a thermoplastic matrix polymer or polymer mixture partially compatible therewith and having a solubility parameter > 8.6 (cal/ cm3)1/2, in order to obtain mouldable polymer blends. The latter are suitable for producing moulded articles particularly for electrical conductors semiconductors, or photoconductors. A suitable apparatus for producing the polymer blends comprises an extruder or kneader through whose barrel one or more sonotrodes project into the transformation zone.
