Abstract: The polyamide has units of formula: -(HNCR1RCHR2CO)n-(where R and R2 are H, alkyl, alkenyl, aryl, R, is alkyl, alkenyl or aryl, R1 and R2 can form together an (unsat) cycloaliphatic gp with not more than 10C, n is 300 - 50,000 pref. 300-10000) in the main chain. The polyamide is pref. prepd. by polymerising a lactam of formula: The polymers have high melting pts. and low stability. The fibres and foils have high tearing and twisting coefficients.
