Abstract
This invention is directed to a polymeric thermo-sensitive material which comprises a polyamide composition containing compounds of sulphur-contained compounds or phosphorous acid ester, and which is smaller in polarization in the application of direct-current electric field, higher in temperature detection function, does not cause flexibility deterioration due to heating operation and is less in hygroscopicity. A composition containing thiophosphorous acid ester and bis(hydroxyphenyl) sulfide derivative from a group of the phosphorous acid ester is particularly superior in quality.
