The photolysis mechanism of polyester of succinic acid with N—β-hydroxyethyl 2,2,6,6-tetramethyl-4-hydroxy piperidine (Tinuvin-622) has been studied by instrumental analysis. The results show that Tinuvin-622 can be easily photolysed. Based on the results of IR, NMR, ESR, GPC, GC, MS, the photolysis mechanism of Tinuvin-622 has been proposed.
