Abstract
The pho,o-oxidation reactions 3B cis-polyisoprene, polybutsdiene, siiyrene- PolybuGadiene (25 % azyrene- 75 % polybucadiene) and polychlor oprerle weze studied in absence sna presence of sensitize^ c~inpounds such as benzophenone, anthracene and ruorene as well as i n absence and presence of B-car otene + diphenyl arnine and benzidine as s i n g l e t oxygen quenchers, It wcs found t h a t che u~v. ir-adiation of these polymers during passing constant flow rate of oxygen, an amount of hydroperoxide was formed during long i2radi a t i o n time. The concentra ion of hydxoper oxide groups is increased by increasing both the concentration of s e n s i t i z e r ~nd h e number of quanta absorbed. It was found thac zuarene is i;he best sensi::iesr in $his pho~kooxidation rezcbion fol lowed by anahz~cencea nd ~hela tlzer is a b e t t e r sensiSizer than benzophenone. This effect i s attribu’ked bo the physical and chemical generation of singlez; oxyben in case of both an’khracene and rubrene which have a b i l i t y t o form endoperoxides and subsequencely decompose during ;he reaction giving s i n g l e t oxygen species. In ;he case of benzophenone, s i n g l e t oxygen generation i s due 20 physical process.
