Abstract
PURPOSE: To provide a heat-sensitive element in which impedance characteristics are remarkably changed with temperatures, by a method wherein liCl is blended with a specified polyamide resin.
CONSTITUTION: (B) 100W6,000ppm, perf. 300W3,000ppm (calculated as Li) of LiCl is blended with (A) a polyamide resin contg. not more than 14 amide gp. per 100 carbon atoms (e.g. a polyaminoundecamide). The mixt, is melt-kneaded and then molded into a rod or a sheet to form the desired heat-sensitive element.
EFFECT: Electrical properties are remarkably changed with temperatures. The amount of the element is not changed with time by bleedout. The element does not corrode aluminum and copper which are used for signal conductors.
