Zusammenfassung:	PURPOSE:To obtain the title material useful as a thermister which is lowly hygroscopic and excellent in heat resistance, electrical properties, etc., by mixing a vinyl chloride copolymer with an ethylene/vinyl acetate copolymer and a cationic antistatic agent. CONSTITUTION:A polymeric thermister prepared by mixing 100 pts.wt. copolymer, obtained by copolymerizing 80-98wt.% vinyl chloride with 20-2wt.% ethylene and/or propylene, with 5-40 pts.wt. ethylene/vinyl acetate copolymer and 1-5 pts.wt. cationic antistatic agent. Examples of the cationic antistatic agent to be used include those based on amine, imidazoline, ethylene oxide or propylene oxide adduct, and quat. ammonium compound.
