NMR as a probe of nanostructured domains in ionic liquids: Does domain segregation explain increased performance of free radical polymerisation?

Abstract

Rotating frame nuclear Overhauser effect spectroscopy (ROESY) has been used to probe the chemical environment in dialkyl-imidazolium ionic liquids. A qualitative use of the distance dependence of the rotating frame Overhauser enhancement (ROE) has shown that reactants and intermediates have variable affinities for the distinct domains that are proposed within ionic liquids. A model system based on the free radical polymerisation of methyl methacrylate (MMA) has been developed to investigate any differing affinities, and to investigate the hypothesis that segregation of species between domains within the ionic liquid structure is contributory towards the generation of unexpectedly high rates of polymerisation and final polymer molecular weights.
