New dispersants from functionalisation of macromonomers from catalytic chain transfer polymerisation

Lead Research Organisation: University of Warwick
Department Name: Chemistry


The project will focus on varying backbone monomers favouring copolymerisation of the macromonomer vs chain transfer. This work will feed into a Lubrizol internal approach being taken for internal dispersant developments. As CCT produces very high level of chain end unsaturation functionalisation reactions of the macromonomers e.g. through hydrosilation or epoxidation potentially offers a route to a range of reactive acrylic building blocks. Lubrizol have offered a fast track to pilot plant and application trials for promising candidates.

Description Paint formulations for the automotive industry require 3 elements: a pigment, a pigment carrier (solvent), and a dispersant. The dispersant is probably the more important component of the formulations as it allows for the pigment to stay in solution. If the dispersant does not work as expected. The paints degrade very quickly by for example fading or lumping etc..
Traditionally, the solvents used consists in organic solvent that are a hazard to human health and the environment. Since the early 2000's, there has been an effort to produce dispersant that would allow the dispersion of pigments in water instead of these organic solvents. The work that was achieved thanks to this award led to the development of a highly scalable dispersant that is water-soluble and has shown great efficiency in dispersing a range of different pigments in water.
Exploitation Route The outcomes of this funding have allowed a synthesised product to potentially be taken to market. This was shown by providing a whole new class of dispersant than what is currently on the market, and that has proven to work with a wider range of pigments.
Academically, the project also led to new insights into the functionalisation of polymers by involving a multitude of different reactions in various conditions. As most of the work was carried out with linear polymers, this allows for further studies into the potential of non-linear pigment dispersant with multiple anchors.
