Article published on the design of hyper-branched polymeric dispersion agents

For several years, ChemStream invested in the design of novel nanopigment dispersants, starting from bio-based monomers. The concept is based on the grafting of aliphatic polyester chains, that are built by the co-polymerisation of bio-based monomers, on PEI in the bulk without using solvents.

A mathematical model was developed by the Maastricht University (AMIBM) to determine the optimal polymer composition and synthesis conditions, after which these new dispersants were tested in UV-curable inks by ChemStream.

Nils De Vos, Kamiel Matthyssen and Geert Deroover, as co-workers of ChemStream, made important contributions to this research.
