PREPARATION AND PROPERTIES OF CONDUCTING POLYOLEFINS COMPOSITES

The method of chemically initiated oxidative modification of polypropy lene particles in suspension by pyrrole was used for preparation of co nductive polypropylene/polypyrrole composites. Their properties were c ompared with another type of polypropylene/polypyrrole composites prep ared by melt mixing of pure polypropylene with chemically synthesized polypyrrole and with polypropylene/carbon black composites also prepar ed by melt mixing. The composites were characterized by elemental anal ysis and by rheological testing. The antistatic properties of prepared composites were demonstrated. The electrical and flow properties depe nd on the concentration of filler and on the processing conditions of composites.
