PURPOSE: A new polymer composition is provided which has low specific resistance and high positive temperature coefficient anomaly height. CONSTITUTION: The conduct polymer composition comprises 20- 80 weight % of first polymer component of polyethylene selected from high density polyethylene having 0.95- 0.97 g/cubic cm of density, middle density polyethylene, low density polyethylene, linear low density polyethylene and their mixture, 20- 80 weight % of second polymer component of photo-oriented liquid crystal polymer such as polyvinyl, polysilane, polysiloxane, polyphosphazene having comparing, cinnamoyl, perillic ester side chain, having a functional group for £2+2| cyclization addition reaction and 20- 70 weight % of conductive filler such as carbon black, graphite, metal, metal oxide, glass or ceramics coated with conductive material. |
