In this work, a novel photocurable soybean oil based phosphorus containing oligomer was synthesized with the ring opening reaction between the epoxidized soybean oil and a phosphorus containing reactive monomer (Sipomer PAM-200). Instead of conventional heat and solvent based textile coating techniques, photocuring, which is a time and energy saving and solventless/waterless, environmentally friendly technology, was proposed. The structural characterization of the synthesized oligomer (S-ESBO) was performed by Fourier transform infrared (FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopies. Then the coating formulations were prepared by using the S-ESBO oligomer and various reactive diluents; methyl acrylate (MA, monofunctional), hexanediol diacrylate (HDDA, bifunctional), and 1-vinyl-2-pyrrolidone (NVP, aromatic functional). The effects of the reactive diluent type on the mechanical, thermal, and surface properties of the coated photocured cotton fabrics were all investigated. The overall results demonstrate that the presence of the phosphorus group in the formulation increased the char yield values above 600 °C by inhibiting the spread of heat and pyrolysis products through the fabric sample. The thermal transitions, cotton fabric drapeability, weight loss of the fabrics with abrasion, mechanical and wettability properties were all affected based on the properties (i.e. aromatic, aliphatic, flexible, rigid etc.) of the functional groups of reactive diluents.
