Abstract: Latex nanoparticles from acrylic monomers (made from olive and soybean oil which are significantly different in terms of fatty acid unsaturation amount) were synthesized using miniemulsion copolymerization with styrene and methyl methacrylate. Presence of plant oil-based fragments impacts thermomechanical properties of latex films by decreasing glass transition temperature and creating a plasticizing effect. The thermomechanical properties of resulting latex nanoparticles depend considerably on the amount of incorporated oil-derived fragments. As a result, biobased ingredients make latex copolymers more flexible, improve material film forming properties, and provide flexibility and toughness when compared to the normally rigid polystyrene and poly(methyl methacrylate). In addition, plant oil-based fragments enhance hydrophobicity of the crosslinked latex films and can be considered as additives to reduce water sensitivity of the polymer network.
