Abstract
Interactions during the UV stabilization of cis-1,4-polybutadiene of a hindered piperidine (Tinuvin 770), its analogue hindered nitroxyl radical, 4-hydroxy-2,2,6,6-tetramethylpiperidino-1-oxy, with the UV-absorbers, ortho-hydroxybenzophenone and 2(2′-hydroxy-5-methylphenyl)benzotriazole (Tinuvin P) were investigated by using UV/VI, IR and ESR spectroscopy. Mechanisms for the observed antagonistic effects between the two groups of photostabilizers have been proposed.
