| Abstract: | An oleic acid-based epoxy monomer was synthesized by reacting 2-hydroxyethyl acrylate with epoxy stearic acid and an immobilized lipase. NMR, electrospray ionization mass spectrometry and gel permeation chromatography were used to characterize the intermediates and products. 2-(Acryloyloxy) ethyl epoxy stearate was synthesized with a yield of 87 % w/w. After free radical polymerization, epoxy stearic acid-grafted epoxy polymer with molecular weight of 15,150 g/mol was obtained; the final yield was 81 % w/w. |
