POLYMER TEMPERATURE SENSOR

摘要

High mol. wt. temp. sensor is prepd. by adding the aldehyde condensn. polymer of the phenol cpds. to the polymer metrix which comprises polyamide contg. N-alkyl substd. amide component or ethylamide component. The Fig. 1 showes the wet-resistablity of the phenolic condensn. polymer when the ratio of polyamide and N-substd. amide component is changed.
