Nachhaltige Polymere In der Zuschrift auf S. 4260 ff. beschreiben E. Y.‐X. Chen et al. die organokatalytische Polymerisation von γ‐Butyrolacton. Das Produkt ist ein hochmolekularer, metallfreier Polyester, der vollständig recyclebar ist.
The first effective organopolymerization of the biorenewable “non‐polymerizable” γ‐butyrolactone (γ‐BL) to a high‐molecular‐weight metal‐free recyclable polyester is reported. The superbase tert‐Bu‐P4 is found to directly initiate this polymerization through deprotonation of γ‐BL to generate reactive enolate species. When combined with a suitable alcohol, the tert‐Bu‐P4‐based system rapidly converts...
