Polymer composition containing polyaniline

Abstract

RENOV24001NL / P0 ABSTRACT The invention relates to a method for preparing a masterbatch comprising a thermoplastic polymer and polyaniline, comprising the following steps of a) Dissolving a thermoplastic polymer in a suitable solvent to obtain a thermoplastic polymer solution; b) Adding aniline to the thermoplastic polymer solution; c) Optionally adding a salt, acid, an oxidizing agent and water to the solution of step b) thereby inducing polymerization of aniline to polyaniline (PANI) to obtain a dissolved blend of thermoplastic polymer and PANI; d) Coagulating the dissolved blend of thermoplastic polymer and PANI to obtain a masterbatch of thermoplastic polymer with PANI. Further the invention relates to a masterbatch of a thermoplastic polymer with a finely divided PANI and the use of the masterbatch in obtaining polymer composites.
