description Conductive polymer compositions which exhibit PTC behavior comprising a first polymeric component which may be crystalline, a second component, and a particulate conductive filler. The second component may comprise either a polymer which exhibits side chain crystallization or a crystalline material which has a sharp melting point and has poor physical properties at room temperature and/or exhibits no melt strength at elevated temperatures. The compositions are particularly useful in electrical devices which exhibit "square" resistance vs. temperature characteristics.
