Free radical polymerization of acrylic monomers from plant oils

Most currently available synthesis of polymers fromplant oils are limited to polycondensation and oxypolymerization. Both
mechanisms result in formation of exclusively cross-linked polymers, widely applicable in industrial coatings. Because
of highly hydrophobic nature of triglyceride molecules, the development of waterborne polymeric materials (in particular,
latexes) from plant oils has been challenging. One-step method converts fatty acid esters of vegetable oils into bio-based acrylic
monomers for free radical polymerization. While the vinyl bond of these monomers is reactive in conventional addition chain
polymerization and facilitates macromolecular chain growth, the double bonds of the fatty acid chains are unaffected during
the free radical polymerization. Currently exemplified for soybean, linseed, sunflower and olive oil (possessing remarkably
different compositions of fatty acids in triglycerides) monomers can be applied in the production of latexes that utilize acrylic
monomers and polymers. The plant oil-based monomers offer unique functionality due to nature of double bonds, which
allows forming linear macromolecules as well as “on-demand’ cross-linking, and provides an ability to tune final material
properties, including hydrophobicity. The reactivity ratios of the synthesized monomers in free radical copolymerization with
petroleum-based counterparts, as well as theirs Q-e parameters, indicate that new monomers behave in copolymerization as
conventional vinyl monomers. The resulting copolymers are capable of post-polymerization oxidative reactions to form cross-
linked polymer structures, or of modification of unsaturated fatty acid chains. Specifically, degree of unsaturation in fatty acids
are utilized as a criterion for comparing monomers behavior in addition chain polymerization and copolymerization to yield
biobased polymer latexes.
