Abstract

The increasing importance of sustainability and environmental conservation has led to a significant change in the strategies employed for the synthesis and application of materials. One of the areas with the greatest potential in this regard is the development of bio-based polyesters (PE), which provide a more sustainable alternative to petroleum-derived polymers. In this work, polyesters (PE) have been synthesized from a natural compound, specifically eugenol. A solvent-free methodology was employed, and a comparative study of the efficiency of five different catalysts was carried out. The resulting polymers were characterized using various techniques, including Nuclear Magnetic Resonance (NMR) spectroscopy and Gel Permeation Chromatography (GPC). Furthermore, the thermal properties of the synthesized PEs were analyzed by Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Finally, although the direct recovery of the original monomer could not be achieved, it was demonstrated that these materials are chemically degradable, highlighting their importance in reducing waste accumulation.
