Novel bio-based trifunctional 5-membered cyclic carbonate (Res-TC) resins were synthesized via glycidyl etheration of resveratrol and successive insertion of carbon dioxide to the epoxy groups. The resins were thermally cured with trioxyethylene diamine (TODA), and cured Res-TC/TODA films were prepared. Thermal properties of the cured material were examined by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). The glass transition temperature (Tg) and 5% weight loss temperature (Td5) of the cured Res-TC/TODA were determined to be 15.4oC and 224oC, respectively. These results indicated that the cured material was rubbery at room temperature and easily decomposable at elevated temperature. The elastic modulus, tensile strength, and elongation at break were 850 MPa, 38.3 MPa, and 0.068, respectively, which shows that the cured material was tough and flexible. Shear adhesion strength of the cured materials toward stainless substrates was estimated at 10.8 MPa, indicating their high applicability to adhesives. Examination of the enzymatic degradation of the cured materials revealed their potential degradability by enzymes such as lipase and protease.
