Abstract:
1. A method for hydroxylation, alkoxylation or oxycarbonylation of polymer surfaces, comprising: obtaining photochemical Fenton reaction-derived RO. radicals, reacting said polymer surfaces with said RO. radicals, wherein R of said RO. radicals is selected from the group consisting of a hydrogen, an alkyl group having 2 to 15 carbon atoms, an acyl group —COR′ in which R′ represents an alkyl group having 2 to 15 carbon atoms, and a aroyle group —COAr in which Ar represents an aromatic group having 6 to 15 carbon atoms, said polymer surfaces being different from polymers selected from the group consisting of polymethylmethacrylate (PMMA) and fluorocarbon polymers when R represents a hydrogen, and polymer mixture surfaces, said polymer surfaces comprise monomeric units of which at least 50% among these are aliphatic units.
