摘要：A highly functional unsaturated ester macro monomer was synthesized from soybean oil (SBO), and its chemical structure was confirmed by FT-IR, H-1 NMR, C-13 NMR, and gel permeation chromatography. The monomer was prepared through modifying epoxidized soybean oil (ESO) first with a synthesized precursor, hydroxyethyl acrylated maleate (HEAMA), and then employing maleic anhydride (MA) to modify the produced ESO-HEAMA. The obtained SBO-based monomer (ESO-HEAMA-MA) possessed a C=C bond functionality of 6.75-8.15 per ESO. Effects of styrene concentration, feed ratio, and initiator concentration on the dynamic mechanical properties of the cured bioresins were investigated carefully. When the monomer with the highest C=C bond functionality was used, the cured resins with 20-60 wt % styrene demonstrated cross-link densities of 5.07-9.52 (10(3) mol)/m(3), storage moduli at 25 degrees C of 1.32-2.16 GPa, glass transition temperatures of 69.9-114.1 degrees C, and tensile strengths and moduli of 19.7-33.1 MPa and 1.17-2.11 GPa, respectively. Microstructural morphologies of tensile-fractured surfaces of the cured resins were studied by scanning electron microscopy. Finally, curing behaviors of the resultant resin was studied by differential scanning calorimetry. The developed eco-friendly biomaterials have potential applications in the industry of unsaturated polyester resins.
