Light stabilisers polymer-bound

The mechanistic behaviour of absorbers based on 2-hydroxybenzo-phenone, 2-hydroxyphenylbenzotriazole and salicylates continues to attract much interest. Salicyloyl(3 5-di-tert-butyl-4-hydroxy-benzyDamine is claimed to be the most effective light stabiliser to date for polyethylenewhile effective polymer bound stabilisers based on 2-(2-hydroxyphenyl)-2H-benzotriazole have been made... [Pg.484]

Laser-induced fluorescence data provide a wide variety of detailed information about physical and chemical reactions. Laser-based time-resolved (picosecond) fluorescence spectroscopic techniques have been used to investigate the mechanism of photo-stabilisation by UVAs such as benzophenones, ben-zotriazoles and polymer-bound UV stabilisers [117]. Such ultrafast spectroscopic measurements can provide insight into the dynamics of the primary energy dissipation processes in polymers and polymer additives following light absorption. Excimer LIF spectra of plasticised PVC showed two distinct regions... [Pg.344]
