Fourier transform IR studies of the degradation of polyacrylonitrile copolymers—IV

The results of a Fourier Transform study of the degradation of an acrylonitrile copolymer containing approx. 4 wt% of acrylamide at 160°C under a reduced pressure of 5 × 10−2 Torr, are presented. A mechanism is proposed for the degradation that is consistent with the IR spectral evidence.
