The formation of colour and other chemical changes which take place when Courtelle acrylic fibre is strongly heated in air and in nitrogen are studied in detail. Until conditions are sufficiently severe to cause heavy discoloration, there is little weight loss and only small quantities of ammonia and hydrogen cyanide are evolved. During the later stages there is an increase in uptake of acid and a greatly enhanced sensitivity to strong alkali. It is considered that formation of cyclic –C = N– conjugated structures is the most probable mechanism.
