STABILIZATION AND MODIFICATION OF POLYCAPROAMIDE - Photochemical Reactions in Heterochain Polymers - page 44

With this purpose there were taken derivatograms of dyed samples in comparison with
initial undyed ones. It was noted, that similar dyeing does not greatly effect on the process of
softening of fibre-forming polymer. However, in the range of temperatures 210-220 0 C, that
is in the field of PCA melting there are some disagreements between initial and dyed somples
(Figure 1.21).
