(729i) Bio-Based Thermosets Prepared Using Michael Addition of Furan and Isosorbide Building Blocks

The Michael addition reaction of (meth)acrylates with amines can be used for the preparation of thermosets for coating applications because fast reaction kinetics allow for rapid cure at a low temperature. Furan-based building blocks have been investigated as alternatives to incumbent phenolic systems and have been found to possess good mechanical and barrier properties. Multifunctional furan-based amine cross-linkers and Isosorbide Methacrylate (IM) were used to create thermosets utilizing the Michael addition reaction. The system can be cured at low temperatures in a relatively short period of time while yielding good thermal and mechanical properties due to high functionality of the amine cross-linkers and high reactivity of IM. In this investigation the cure behavior of these new systems was investigated using spectroscopic techniques. The relative reactivity of primary and secondary amine was evaluated and formulations were obtained that resulted in IM conversion greater than 90%.
