We report here the synthesis and spectral characterization of a functionalised linseed oil by grafting succinic anhydride (SA) moieties onto the linseed oil methyl ester (LOME) backbones via ene-reaction with maleic anhydride (MA). The maleinized linseed oil methyl esters (MLOME) were characterized through H-1-, C-13-NMR and FT-IR spectroscopy. The amount of succinic anhydride grafted onto the LOME molecules (maleinization degree) was determined from FT-IR spectral data, on the basis of a calibration curve from synthetic mixtures of LOME and SA in different molar ratios. The functionalization degree was also determined from H-1- and C-13-NMR (semi-quantitative experiments) spectra of MLOME by chemometric calculations.
