摘要： A novel PTC conductive polymer composition is disclosed, which comprises (a) 35 to 60%, by weight of the composition, of a branched polyolefin with a polydispersity index of less than 2.5; and (b) 20 to 45%, by weight of the composition, of conductive particles which have been dispersed in the polyolefin. The PTC composition of the invention has intense, reproducible PTC behavior and is particularly suitable for use in PTC thermistors.
