ABSTRACT:
Circuit protection devices comprising PTC elements and circuits containing such devices. The PTC element includes a crystalline conductive polymer composition comprising a conductive particulate filler grafted to a modified polyolefin. The modified polyolefin comprises a polyolefin having a carboxylic acid or a carboxylic acid derivative grafted thereto. The conductive particulate filler is grafted via an esterification reaction to the modified polyolefin.
