Abstract
PURPOSE: Titled high molecular heat-sensitive material having a high rate of variation of electric resistance with temperature, comprising a polyether esteramide produced from an ω-aminocarboxylic acid or lactam of at least 10C, an α,ω- dihydroxy polytetrahydrofuran and a dicarboxylic acid.
CONSTITUTION: A polyether esteramide is produced from (a) an ω-aminocarboxylic acid or lactam of at least 10C, such as ω-aminoundecanoic acid or particularly laurolactam, (b) an α,ω-dihydroxypolytetrahydrofuran, 1,600W3,000MW, pref., 300W2,200, particularly pref., 500W1,200, and (c) a dicarboxylic acid, pref., 4W30C, such as decanedicarboxilic acid, hexahydroterephthalic acid or terephthalic acid. Then, this high-molecular material is formed into films, etc., which can be used as a high-molecular heat-sensitive material, in electric blankets, electric carpets, etc.
