Abstract Photocurable systems are more effective, faster and require less energy
than conventional thermal curing methods. To facilitate the ongoing transition toward
a biobased economy, photoactive compounds were synthesized from tall oil fatty
acids (TOFA) which is a by-product from wood pulping. In this study, photoactive
monomers were synthesized by two different chemical pathways using oleic acid
and TOFA as raw materials. Firstly, double bonds present in TOFA were epoxidized,
followed by epoxy ring-opening with acrylic acid which introduced photoactive functional groups into the fatty acid backbone. Intermediates and final products were analysed using titration methods (acidic value, epoxy value, iodine… More >
