Traces of ionic liquids (ILs) accelerate the novel imine base/isocyanate (IBI)-mediated radical polymerization of methyl methacrylate (MMA). Both the brutto polymerization rate constant kBr,0 and the activation temperature of IBI mixtures are influenced. Herein, results are reported on the polymerization kinetics of several IBI combinations in the presence of selected ILs whereas a comparison with non-IL containing initiator mixtures is given. The interaction strength of the IL with each IBI component and MMA was determined by means of ATR FT MIR spectroscopy.
