Abstract
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/cm.sup.3).sup.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.
