Thermal influence on structure of polymers with ε-caprolactam units studied by FT-IR spectroscopy (in English)

Polimery 2009, No 5, 347


Summary

Some films obtained from poly(ε-caprolactam) (polyamide 6) and its copolymers with laurolactam (copolyamides 6/12) were submitted to thermal treatment. The most versatile method for characterization of polyamide and its copolymers, i.e., FT-IR spectroscopy, was chosen as a tool in order to determine the possible changes in the structures of polymers. It was observed that the polymers films showed Brill transition during heating.


Key words: ε-caprolactam, laurolactam, polyamide 6, copolyamide, FT-IR spectrum, Brill transition
