Abstract

Novel compositions of matter comprise polymeric materials containing, as a filler therefor, a semiconducting pyropolymeric inorganic refractory oxide material, said compositions being useful in situations which require items such as electrically conductive sheets which possess a given electrical resistance.

Claims

1. A composition of matter comprising a polymeric material containing, as a filler therefor, from about 10% to about 95% by weight of a refractory inorganic oxide having a carbonaceous pyropolymer composited on the surface thereof, said filler having a particle size in the range of from about 0.1 microns to about 100 microns and a resistivity in the range of from about 0.001 ohm-centimeters to about 10¹⁰ ohm-centimeters.

2. The composition of matter as set forth in claim 1 in which said polymeric material is Nylon.

3. The composition of matter as set forth in claim 1 in which said polymeric material is polypropylene.

4. The composition of matter as set forth in claim 1 in which said polymeric material is epoxy resin.

5. The composition of matter as set forth in claim 1 in which said polymeric material is a phenolic resin.
