“…Photooxidation of the methylene adjacent to the amide nitrogen can also occur: The methylene group adjacent to the nitrogen can also undergo photooxidation: The photoxidation mechanisms also account for the formation of aldehydes, formamides, and amide-adjacent hydroxyl groups. The above reaction mechanisms are consistent with those proposed by earlier workers.

“…The above reaction mechanisms are consistent with those proposed by earlier workers. [12][13][14][15][16][17][18] Amide bond scission (a bond between the carbonyl and amide nitrogen) has been proposed by some previous investigators. This would result in the formation of amine end groups, which is clearly contradictory to our data in Table 2 for both UV degradation and heat aging.…”

“…Το NÜ2 ουσιαστικά δεν αντιδρά με τα συστατικά του Paraloid Β-72. Όμως, η ακτινοβολία του υλικού με UV προκαλεί την εξαφάνιση των εστερικών ομάδων και οδηγεί στο σχηματισμό HCOOCH3 και μακρομοριακών δομών που περιέχουν διπλούς δεσμούς στην κύρια αλυσίδα τους [204]. Η αντίδραση του διοξειδίου του αζώτου με τους διπλούς δεσμούς παρουσιάζεται στο παρακάτω σχήμα.…”
