Effective Ligand Design: Zinc Complexes with Guanidine Hydroquinoline Ligands for Fast Lactide Polymerization and Chemical Recycling. [PDF]

open access: yesChemSusChem, 2022
Specific design: Using a hydroquinoline backbone for zinc guanidine complexes in the ring‐opening polymerization of lactide results in an enormous activity increase compared to their aromatic counterparts. Not only is the complex very active in the polymerization of lactide, but it also catalyzes the chemical recycling process of solvolysis.

Open- and Closed-Loop Recycling of Polyesters and Post-Consumer Waste Under Industrially Relevant Conditions Using Bisguanidine Organocatalysts. [PDF]

open access: yesChemSusChem
The chemical recycling of polylactide (PLA), polyethylene terephthalate (PET), and polycaprolactone (PCL) is performed using bisguanidine organocatalysts. Intensive kinetic studies of the methanolysis and ethanolysis of PLA were performed. The most active organocatalyst was successfully applied in the depolymerization of ternary plastic mixes of PLA ...

A Multitool for Circular Economy: Fast Ring‐Opening Polymerization and Chemical Recycling of (Bio)polyesters Using a Single Aliphatic Guanidine Carboxy Zinc Catalyst

open access: yesChemSusChem, Volume 16, Issue 12, June 22, 2023., 2023
Complex as multitool: A new aliphatic N,O‐guanidine ligand and its ZnCl2 complex are presented. The complex shows high catalytic activity towards both ring‐opening polymerization of lactide in the monomer melt and methanolysis of polylactide, as well as other (bio)polyesters.

The Concept of ‘Information’: An Invisible Problem in the GDPR

open access: yesSCRIPTed: A Journal of Law, Technology & Society, 2020
Information is a central concept in data protection law. Yet, there is no clear definition of the concept in law – in legal text or jurisprudence. Nor has there been extensive scholarly consideration of the concept.
