Abstract
This paper reports on the selective hydroperoxidation of unsaturated elastomers by using singlet oxygen photochemically produced (sensitization by anthracene at 365 nm). Hydroperoxide groups were characterized by using derivatization by nitric oxide and dimethyl sulfide. Grafting was performed by decomposing of hydroperoxide groups in the presence of acrylate monomers or nitroxyl radicals. According to the substituents, in acrylate hindered amine stabilizers (HAS) can be obtained. In the last part, the effect of grafted HAS on photo and thermal ageing of the parent elastomer is reported.
