Monitoring the radiation-induced bulk polymerisation of methyl methacrylate with N-(1-pyrene)maleimide

The fluorogenic probe N-(1-pyrene)maleimide, MPy, exhibits a fluorescence response directly correlated to the monomer conversion in the radiation-induced polymerisation of methyl methacrylate (MMA). In the low-dose region, the ratio between propagation rate constants for the cross-over reaction in w...

Zusammenfassung:The fluorogenic probe N-(1-pyrene)maleimide, MPy, exhibits a fluorescence response directly correlated to the monomer conversion in the radiation-induced polymerisation of methyl methacrylate (MMA). In the low-dose region, the ratio between propagation rate constants for the cross-over reaction in which a MMA radical chain-end reacts with MPy relative to the homopolymerisation reaction of MMA is found to be 1.38±0.15.
