Polyethylene furan-2,5-dicarboxylate
polymer
Polyethylene furan-2,5-dicarboxylate, also named poly(ethylene furan-2,5-dicarboxylate), polyethylene furanoate and poly(ethylene furanoate) and generally abbreviated as PEF, is a polymer that can be produced by polycondensation or ring-opening polymerization of 2,5-furandicarboxylic acid (FDCA) and ethylene glycol. As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). PEF has been described in (patent) literature since 1951, but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based replacement for purified terephthalic acid (PTA) in 2004.
Benefits over PET
One life-cycle assessment showed that replacing PTA in the production of PET by bio-based FDCA for the production of PEF has a potential for significant reductions in greenhouse gas (GHG) emissions and non-renewable energy use (NREU). Furthermore, PEF exhibits an intrinsically higher gas barrier for oxygen, carbon dioxide and water vapor than PET and is therefore an interesting alternative for packaging applications such as bottles, films and food trays.
The public source identifies “Polyethylene furan-2,5-dicarboxylate” as polymer. This brief keeps that definition visible, then builds a research path around Polyethylene, furan-2 and 5-dicarboxylate.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Polyethylene furan-2,5-dicarboxylate”, the useful work is to connect “polymer” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 28, 2023. The linked authority identifier is Q25112485. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1951 and 2004.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
