Summary: The upgrading of sustainable materials to replace traditional petroleum resources is a significant challenge. A bio-based building material provides the foundation for the bio-market and green economy. 2,5-Furandicarboxylic acid (FDCA) shows potential as a substitute for terephthalic acid (TPA), and recent research has focused on the synthesis, modification, and functionalization of bio-based polyesters based on FDCA.

Summary: A thermoplastic poly(cycloacetal-urethane) was successfully prepared by copolymerizing a rigid diol with potentially bio-based polytetrahydrofuran, resulting in high thermal stability and tunable glass transition temperatures. The polymer showed a relatively high pyrolysis char residue, indicating potential flame resistance, and could be melt-spun into homogeneous fibers with ease for further hydrolysis under acidic conditions.

Summary: This literature review discusses the characteristics and techniques of film-type packaging and polysaccharide-based coatings in the food industry. Polysaccharides, as renewable and biodegradable alternatives to synthetic plastics, have the potential to reduce their usage. However, the barrier and mechanical properties of polysaccharide packaging remain a challenge for the food industry.

Summary: Polyesters with high T-g from renewable resources are crucial for expanding their application range. A series of copolyesters, PBSF, were synthesized from BHEPS, BDO, and FDCA, with increasing BHEPS content leading to higher T-g but lower M-w. PBSF-65 was identified as a promising polyester for various applications requiring high transparency and heat resistance, with specific properties suitable for baby bottles, children's toys, kitchen appliances, and beverage packaging.

Summary: Bio-based fumaric acid is a key monomer for the fabrication of high-performance and thermal-induced degradation polymers. Copolyesters of poly(butylene 2,5-furandicarboxylate/fumarate) have high molecular weight and interesting properties. The combination of trans C=C bonds and the conjugated effect result in enhanced elastic modulus, tensile strength, gas and water diffusion barrier, as well as improved hydrolysis resistance.

Summary: In this study, a bio-based solvent-free vitrimer was successfully synthesized using epoxidized castor oil (ECO) through a UV-curing process. Real-time Fourier-transformed infrared spectroscopy and photo-DSC were used to monitor the UV-curing process. The UV-cured polymer networks exhibited thermo-activated bond exchange reactions due to the presence of a transesterification catalyst. The ECO-based vitrimer showed high thermal resistance and good mechanical properties, making it a promising starting point for sustainable vitrimers.

Summary: Amorphous and semi-crystalline polyester polyols based on a novel, low cost, bio-based 1,5-pentanediol (Bio-PDO) were synthesized and formulated into coatings and adhesives. Bio-PDO shows potential as a more cost-effective and sustainable alternative to HDO. The effects of common bio-based impurities on polyester polyols were investigated, with high levels of tetrahydrofurfuryl alcohol found to have deleterious effects on polyol hydroxyl functionality. Low impurity levels (<2 wt %) are not expected to have negative impacts in leading bio-PDO processes.

Summary: Porphyrins and their derivatives exhibit useful properties in catalysis, photovoltaics, and biomedicine. By synthesizing porphyrin-containing polymers, the applications of porphyrins can be expanded. An enzymatic two-step method involving ring-closure and ring-opening reactions was used to successfully synthesize polyesters with porphyrin moieties, demonstrating good thermal stability and optical properties similar to their precursor porphyrins.

Summary: A series of aliphatic-aromatic polyesters were successfully synthesized in this study, which possess the advantages of being renewable, degradable, and abundant. The properties of the copolyesters can be adjusted by varying the length of the carbon chains of the dicarboxylic acid moieties. Thermal analysis showed that these copolyesters exhibit good thermal stability, mechanical properties, and biodegradability. The investigation of eco-toxicity demonstrated their low toxicity in natural habitats, contributing to carbon neutrality and sustainable development of bio-based plastics.
