Is it possible to control kinetic rates of radical polymerisation in ionic liquids?

This work predicted propagation rates of free radical polymerisation in clusters of ionic liquids: stabilisation of the propagating radical and deactivation of the monomer were found to be the main factors in controlling kinetic rates, allowing for controlled free radical polymerisation in ionic liquids.

The impact of sulfur functionalisation on nitrogen-based ionic liquid cations

XPS is used to investigate the impact of sulfur containing substituents on the electronic structure of a series of N-based cations, all with a common anion, [NTf2]. The experimental data is complex and cannot be easily deconstructed, DFT provides critical insight into bonding and electronic structure for each system studied.
