PURPOSE: The titled material, consisting of a copolyamide, prepared by polycondensing a mixture of a lactam or ω-aminocarboxylic acid with an N-substitution product thereof, having flex resistance, and suitable for a temperature sensing apparatus. n CONSTITUTION: A high polymer temperature sensitive material prepared by polycondensing (B) 95W60pts.wt. mixture consisting of 5W50wt% N-alkyl-substituted lactam, e.g. a caprolactam substitution product, expressed by formula I (R is 4W30C alkyl; n is an integer 5W13) or N-alkyl substitution ω-aminocarboxylic acid expressed by formula II (n is an integer 5W13), e.g. caprolactam, or ω- aminocarboxylic acid expressed by the formula H 2 N-(CH 2 ) n -COOH in the presence of (A) 5W40pts.wt. polyolefin resin containing carboxyl groups. n COPYRIGHT: (C)1983,JPO&Japio |
