N2 - The depletion of fossil fuel feedstock and the deterioration of the planet environment stimulate the search for alternative renewable raw materials to synthesize monomers and polymers. A promising renewable resource for the synthesis of the polymers is a wide range of plant oils. In this study, we have synthesized the monomer via transesterification of triglycerides of high oleic sunflower oil by using N-(hydroxyethyl)acrylamide. The presence of the acryloylamide moiety and oleic acid acyl fragment in the high oleic sunflower oilbased monomer molecule was confirmed by means of infrared and nuclear magnetic resonance spectroscopies. Then, the plant oil-based homopolymers with an average molecular weight of (19-21)·103have been synthesized using free radical polymerization mechanism in a toluene solution (750C, azobisisobutyronitrile as an initiator). Stable latexes with unimodal particle size distribution were obtained using miniemulsion polymerization (with an average molecular weight of latex polymer of 33?103). Based on the established polymerizability of the synthesized monomer, we showed the synthesized monomer can be copolymerized with commercial monomers to form copolymers with adjustable physical-mechanical properties for the production of hydrophobic coatings, adhesives, surfactants, cosmetic products, composites, etc.
