Acrylic plant oil-based monomers with high content of oleic acid esters

Abstract

New acrylic monomers were obtained via transesterification of olive, canola, and high-oleic soybean oils by N-hydroxyethylacrylamide. The kinetic features of homopolymerization of these monomers were studied and the influence of linoleic (C18: 2) and linolenic (C18: 3) acid esters on the polymerization rate and the molecular weight of homopolymers were compared. It was found that the chain transfer and propagation rate constants increase in monomer’s range: olive (CM = 0.016) <high-oleic soybean (CM = 0.018) <canola (CM = 0.025). Features of homopolymerization are associated with varying degrees of unsaturation of fatty acid fragments.
