This study examined the photostabilization of Azadirachtin-A (Aza-A) when exposed to ultraviolet light in the presence of some natural absorbers. Aza-A extract solutions with and without natural UV light absorbers i...
There is a powerful market-need for superfast disperse dyes in special use, e.g. for automotivefabrics. The photochemical fading reactions of dyes are often very complicated, and no singlphotodegradation pathway can b...
It was first proposed by Oster in 1956 that polyethylene could be crosslinked with ultraviolet fight in the presence of some photosensitizers. But the photocrossfinking method was not used in industry for a long perio...
Ⅰ. INTRODUCTION The mechanisms of the photostabilizing effect of hindered amines, based on 2, 2, 6, 6-tetramethylpiperidine, have recently been studied repeatedly. The suggested mechanisms have included production of...
