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

ChemSusChem, 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.

Linking Research Data with Physically Preserved Research Materials in Chemistry [PDF]

Scientific Data
Results of scientific work in chemistry can usually be obtained in the form of materials and data. A big step towards transparency and reproducibility of the scientific work can be gained if scientists publish their data in research data repositories in ...

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

ChemSusChem, 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.

Open Loop Recycling – Guanidine Iron(II) Polymerization Catalyst for the Depolymerization of Polylactide

Chemistry – An Asian Journal, Volume 18, Issue 5, March 1, 2023., 2023
Versatile Allrounder: We report the first iron catalyst active in the selective alcoholysis and aminolysis of PLA using different nucleophiles. Having the increasing plastic waste problem and the acute danger imposed by climate change in mind solvent‐free alcoholysis and catalyst recycling were investigated.

Taking the Next Step—Model‐Based Analysis of Robust and Non‐Toxic Zn Catalysts for the Ring Opening Polymerization of Lactide in the Polymer Melt

Advanced Sustainable Systems, Volume 7, Issue 2, February 2023., 2023
This article reports the development of a simulation model for the ring‐opening polymerization of lactide with nontoxic “asme”‐type Zn catalysts. The influences of various input parameters are investigated experimentally and model‐based. The generality of the developed model for other “asme”‐type Zn catalysts is validated with a second catalyst ...
