This critical review considers the extensive research and development dedicated, in the last years, to a single polymer, the poly(ethylene 2,5-furandicarboxylate), usually simply referred to as PEF. PEF importance stems from the fact that it is based on renewable resources, typically prepared from C6 sugars present in biomass feedstocks, for its resemblance to the high-performance poly(ethylene terephthalate) (PET) and in terms of barrier properties even outperforming PET. For the first time synthesis, properties, and end-life targeting—a more sustainable PEF—are critically reviewed. The emphasis is placed on how synthetic roots to PEF evolved toward the development of greener processes based on ring open polymerization, enzymatic synthesis, or the use of ionic liquids; together with a broader perspective on PEF end-life, highlighting recycling and (bio)degradation solutions.

这项重要的评论考虑了过去几年中针对单一聚合物（通常简称为PEF的聚2,5-呋喃二甲酸乙烯酯）的广泛研究与开发。PEF的重要性源于以下事实：它基于可再生资源，通常由生物质原料中存在的C6糖制成，与高效聚对苯二甲酸乙二醇酯（PET）相似，并且在阻隔性能方面甚至优于PET。首次严格审查了合成，性能和最终寿命目标（一种更具可持续性的PEF）。重点放在PEF的合成根如何向基于开环聚合，酶促合成或使用离子液体的绿色工艺发展的方向发展；加上对PEF使用寿命的更广阔视野，
