A Perspective on PEF Synthesis, Properties, and End-Life

Frontiers in Chemistry, 2020
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.

Interactions of PP-PET blends modified by montmorillonite with different polarities

Polímeros, 2022
This paper describes the effects of adding organic montmorillonite clays (MMT) with different polarities (one polar and one non-polar) in recycled poly (ethylene terephthalate) (PET) and polypropylene (PP) blends. Styrene-Ethylene/Butylene-Styrene-maleic

Study of the glass transition in the amorphous interlamellar phase of highly crystallized poly(ethylene terephthalate)

, 2010
Poly(ethylene terephthalate) (PET) is a semi--crystalline polymer that can be crystallized to different degrees heating from the amorphous state. Even when primary crystallization has been completed, secondary crystallization can take place with further ...

Structural insight into catalytic mechanism of PET hydrolase

Nature Communications, 2017
Poly-ethylene terephthalate (PET) is a widely used plastic which accumulates in the environment with detrimental consequences. Here the authors report crystal structures of a PET-hydrolyzing enzyme from the microbe Ideonella sakaiensis bound to substrate

Pivalolactone, 2. Copolyester synthesis via interchange reactions with polypivalolactone [PDF]

, 1993
The synthesis of copolyesters via interchange reactions of polypivalolactone (PPVL) with several compounds was studied. The synthetical procedures are two-stage melt processes: in the first stage ester bonds in the polymer chain are cleaved and new ...
