Abstract

This project aims the synthesis and characterization of new biopolymers using triacylglycerol sources (linseed, grape seed, baru and macaw oils) as well as terpenes and terpenoids (limonene, myrcene, and abietic acid), which are all renewable sources. They will be modified by maleinization, epoxidation and carbonatation reactions, producing renewable monomers with high reactivity. Thereafter, these monomers will be reacted with polythiol systems by thiol-ene reaction. The renewable monomers will be also reacted with disulfides molecules by heating or light (UV or blue). All syntheses will follow the Green Chemistry Principles. In addition, it is important to emphasize that this project aims to add a value in Brazilian bio-commodities. The purpose of reactions is to produce polymers to be applied in 3D printer, and present properties such as malleability, shape memory, fluorescence, and self-healing. The monomers as well as the biopolymers are going to be characterized by: Simultaneous Thermogravimetric/Derivative Thermogravimetry-Differential Thermal Analysis (TG/DTG-DTA), Differential Scanning Calorimetry (DSC), Scanning Electronic Microscopy (SEM), Dynamic Mechanical Analysis (DMA), Middle Infrared Spectroscopy (MIR), Ultraviolet and Visible Light Spectroscopy (UV-Vis), Nuclear Magnetic Resonance (1H-RMN and 13C-RMN), High Resolution Mass Spectrometry (HRMS), as well as swelling process.
