Vanillin and vanillyl alcohol were modified into methacrylated derivatives. The structures of vanillin-based monomers were characterized by NMR and FTIR. Renewable polymers were prepared from these vanillin-based monomers. The effects of structure and functionality of the vanillin-based monomers on the thermo-mechanical properties of the resulting polymers were investigated and discussed. Polymers from methacrylated vanillyl alcohol (MVA) demonstrated greater storage moduli, higher glass transition temperatures, and thermal resistance than those from methacrylated vanillin (MV) because of the different functionalities of their monomers.
