Abstract In this paper, a fully bio-based vinyl oligomer with high functionalities was successfully prepared from rapeseed oil by three modification steps: epoxidation of rapeseed oil, solvent-free and catalyst-free ring opening by 10-undecylenic acid followed by esterification with 10-undecenoyl chloride. Then, the renewable polymers were prepared by photo-polymerization of these modified vegetable oils with typical thiol monomers: pentaerythritol tetrakis (3-mercaptopropionate), pentaerythritol tris (3-mercaptopropionate) and 1,2-ethanedithiol. The synthesis of the vinyl oligomer was monitored by nuclear magnetic resonance and Fourier-transform infrared spectroscopy. The average number of the carbon-carbon double bonds of the resulting vinyl oligomer is high to be 7.2. The kinetic… More >
