摘要 |
The present invention concerns the use of RO. radicals, R being a hydrogen, an alkyl group having 2 to 15 carbons, an acyl group—COR′in which R′represents an alkyl group having 2 to 15 carbons, or an aroyl group—COAr in which Ar represents an aromatic group having 6 to 15 carbons, for the hydroxylation, alkoxylation or oxycarbonylation of polymer surfaces, the said polymers being different from polymers chosen from: polymethylmethacrylate (PMMA) and fluorocarbon polymers when R represents a hydrogen, or of polymer mixture surfaces, notably hydrophobic ones, the said polymers consisting in monomeric units of which at least 50% among these are aliphatic units, and the said RO. radicals being generated by electrochemical or photochemical means.
