Abstract Nowadays, with the massive increase in consumption of polymeric materials, the demand for raw materials and products that are allied to the environment and do not contribute to its degradation is undoubtedly a goal to be achieved by humanity. In this context it becomes necessary that new models of synthesis and products be developed and seek to contemplate the principles of Green Chemistry. As most polymeric materials come from finite sources such as petroleum and natural gas, glycerol and maleic anhydride emerge as proponents of green inputs for their production. In addition, the use of polyols and polyamines for the production of biopolymers with properties similar to those from non-renewable sources has been producing materials of high technological interest. From this scenario, the present work will aim to synthesize and characterize new biopolymer materials from a reactive monomer, obtained by the reaction between maleic anhydride and glycerol (a waste product from biodiesel production), reacted with polyamines or polythiols. All synthetic routes will be optimized whenever possible, trying to follow the principles of Green Chemistry. The characterization of the starting reagents as well as the final products will be done using the following techniques: simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), mid-infrared absorption spectroscopy (MIR), dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). From the results of the characterizations during the project, it will be possible to determine the best application of the new materials, for example, the synthesis of photocurable monomers to be applied in 3D printers. | |
