| Abstract: | The photostabilizing effect of 1, 2, 2, 6, 6-pentamethyl-4-hydroxy-piperidine(PMP) on polypropylene (PP) films has been investigated. Experimental results further confirm the two step stabilizing mechanism of PMP as suggested in our previous paper.In PP film PMP is first transformed into its N-oxide, and this is then transformed into 2, 2, 6, 6-tetramethyl-4-hydroxy-piperidine-N-oxyl. |
