IR spectroscopy of polyamide libres graded with vinyl monomer


Polimery 1993, No 7, 315


DOI: dx.doi.org/10.14314/polimery.1993.315

Summary

The results of IR-spectroscopic investigations on the site of grafting of poly(acrylic acid), poly(itaconic acid) or poIy(2-vinylpyrydine) chains onto polyamide fibres by the method of thermal initiation were presented. Changes in the amide band at 1650 cm'1 and invariance of the methylene band at 4000 cm'1 are a proof that active centres are formed on nitrogen atom of amide group of polyamide-6.
