Abstract

The kinetics atom transfer radical polymerization (ATRP) of n-butyl acrylate, using the Cu(I)Br/N,N,N ′,N ′,N″-pentamethyldiethylenetriamine catalytic system and methyl-2-bromopropionate as initiator, is studied. The orders of the initiator, activator and deactivator are estimated for two systems – one close to bulk conditions (5 vol.-% toluene added), and another with 10 vol.-% N,N-dimethylformamide added. The former system gave non-integer orders for initiator and activator, while the latter gave orders of unity for both of these reactants. The second system gave a non-linear response for the deactivator.
