Abstract: | The synthesis and characterisation of a novel family of unsaturated polyesters (UPs) and their crosslinked resins (UPRs) based on 2,5-furandicarboxylic acid (FDCA) are reported. Their original features stem from the use of FDCA as the aromatic monomer, and also from the fact that UPs are entirely based on renewable resources, oppositely to most reported materials which are typically based on petrochemicals or instead they are derived from both petrochemicals and a percentage of renewables. Additionally, instead of styrene, 2-hydroxyethylmethacrylate (HEMA) was used as the reactive solvent to obtain the UPRs. These novel resins showed adequate thermal and mechanical behavioural tendencies similar to petrochemical ones, namely high glass transition temperature (up to 104 degrees C) and good thermal stability (up to 230 degrees C). These characteristics enhance their prospects of being a successful renewable-based material. |
