Spectroscopic quantification of kinetic rate constants for epoxy-acrylate hybrid photopolymerisation

摘要

It is well-known that cationic polymerisation is affected by atmospheric moisture. Water can have a number of effects, including decomposition of the photoinitiator and participation in the propagation reactions. In a system containing only epoxide monomers, the propagation reaction proceeds via the active chain end mechanism, but if a nucleophilic species is present, then a secondary pathway, referred to as the activated monomer mechanism, becomes available.
