Ring-opening polymerization of ethylene brassylate in reactive extrusion and its end-of-life options

Polymer Degradation and Stability
Polyesters synthesised from renewable monomers via intensified and industrially relevant processes provide nowadays a science-to-technology breakthrough, especially if they offer a suitable end-of-life scenario for a circular economy. In this work bio-based macrolactone ethylene brassylate was polymerized by reactive extrusion and the properties of the

Ethylene brassylate as a biobased plasticizer for poly(lactic acid): Evaluation of mechanical, thermal, and biodegradation properties

International Journal of Biological Macromolecules
Poly(lactic acid) (PLA) is a bio-based polymer with high potential; however, its inherent brittleness restricts its practical applications. This work evaluates ethylene brassylate (EB), a macrocyclic diester of natural origin, as a plasticizer for PLA at 5-20 wt%.

Charting the landscape of the environmental exposome

iMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

Synthesis of Semi‐Aromatic Di‐Block Polyesters by Terpolymerization of Macrolactones, Epoxides, and Anhydrides

ChemCatChem, Volume 13, Issue 14, Page 3303-3311, July 21, 2021., 2021
All in one: Novel block polyesters, which have one polyethylene‐like block originated by the ROP of a macrolactone and a semi‐aromatic polyester second block derived from the ROCOP of cyclohexene oxide and phthalic anhydride, were produced in a one‐pot procedure. Abstract In this contribution, the catalytic behavior of a phenoxy‐imine aluminum catalyst
