“…A wide range of chemical modifications has been explored so far. The 65 most usual methodologies involved the modification of the double bonds into epoxy functions (epoxydation 36 ), (meth)acrylate functions (acrylation of alcohol 37 or epoxy groups 38 ), acid functions (oxidation 39 ), succinic anhydride group (maleinisation 40 ) and others.…”

International audienceThe synthesis and self-assembly of amphiphilic polymers based on unsaturated vegetable oils and poly(2-methyl-2-oxazoline) (POx) are reported. Two architectures of lipopolymers were explored starting from fatty methyl esters and raw vegetable oils. These latter were converted into macroinitiators for cationic ring-opening polymerization (CROP) of 2-methyl-2-oxazoline. Firstly, a thiol-ene coupling reaction in the presence of mercaptoethanol under UV irradiation was performed to introduce hydroxyl groups that were further transformed into initiating species used for cationic polymerization. According to this strategy, various lipopoly(2-methyl-2-oxazoline)s (LipoPOx)s with different lipidic/POx ratios were successfully obtained and characterized by 1H NMR, SEC and MALDI-Tof analyses. Finally, the self-organization of the LipoPOx was studied using dynamic light scattering (DLS). Well-shaped nanoparticles were obtained with characteristic radii of 4.3 and 10.2 nm for the fatty ester- and triglyceride-based lipopolymers, respectively. The latter value is about twice the former one due to the higher lipidic fraction of the triglyceride-based polymer that promotes hydrophobic interactions. The relaxation time distributions of both systems were found to be monomodal indicating monodisperse colloidal suspensions

Mass spectra of a set of six vinyl monomers derived from stearic acid, each representative of one of the following groups: Vinyl ester (RCOOCHCH2), allyl ester (RCOOCH2CHCH2), acrylic ester (RCH2OCOCHCH2), methacrylic ester (RCH2OCOC[CH3]CH2), allyl ether (RCH2OCH2CHCH2), and vinyl ether (RCH2OCHCH2), where R is CH3(CH2)16‐ are discussed with respect to the influence of the chemical environment on their fragment pattern.
