This paper presents the study of the functionalization reactions of the linseed oil (LO) structure. The main purpose of this study was to obtain oil-based monomers that meet both "green chemistry" properties and reactive sites for the polymerization and also to possess a hydrophilic character. Functionalization of LO chains was achieved by a three step reaction involving sequentially: double bonds epoxidation, partial methacrylation of the epoxy rings and polyethyleneglycole (PEG) grafting by opening of the epoxides unreacted in the previous stage.
