Preparation and properties of conducting polyolefins composites

The method of chemically initiated oxidative modification of polypropylene particles in suspension by pyrrole was used for preparation of conductive polypropylene/polypyrrole composites. Their properties were compared with another type of polypropylene/polypyrrole composites prepared by melt mixing of pure polypropylene with chemically synthesized polypyrrole and with polypropylene/carbon black composites also prepared by melt mixing. The composites were characterized by elemental analysis and by rheological testing. The antistatic properties of prepared composites were demonstrated. The electrical and flow properties depend on the concentration of filler and on the processing conditions of composites.
