Functionalized vegetable oils as precursors for polymers by thiol-ene reaction

• Single step bio-based products by click chemistry.
• Thiol-ene of mercaptanized soybean oil and functionalized allyl compounds.
• Polyamines, epoxides, isocyanates, isothiocyanates and silicon compounds.
• Precursors for foams adhesives, coatings, sealants and elastomers.

A range of vegetable oil derivatives with hydroxyl, amine, isocyanate, isothiocyanate, epoxy and silane terminal groups, useful for making new bio-based polymers, were synthesized from mercaptanized oils and different allyl organic compounds by thiol-ene reaction. All products were low viscosity liquids of light yellow color except amine containing oil, which was a low melting solid. Novel functionalized oils had 3–6 functional groups per mole and were suitable for rigid and flexible polymer products.
