The SP–PLP–EPR technique
has been used to measure
Cu<sup>II</sup>-mediated ATRP deactivation and Cu<sup>I</sup>-mediated
organometallic reactions for butyl acrylate (BA) polymerization. The
deactivation rate is by more than 1 order of magnitude higher than
in dodecyl methacrylate (DMA) polymerization, thus enabling well-controlled
ATRP despite the enhanced BA propagation rate. The organometallic
reaction of Cu<sup>I</sup> with BA radicals was found to play a role
only with highly active Cu catalysts, as demonstrated for the Cu/TPMA-mediated
ATRP of BA.
