[en] The living-radical polymerization of n-butyl acrylate, moderated with TEMPO, is shown to proceed in a controlled fashion in the presence of a series of α-hydroxycarbonyl compounds with different organic bases. The best results were obtained with glyceraldehyde dimer in the presence of pyridine. These results further support the suggestion that the difficulty of polymerizing acrylate monomers in the presence of TEMPO is related to the excess buildup of TEMPO due to a small amount of polymer chain termination and to a lesser extent on the higher bond dissociation energy of the TEMPO acrylate bond relative to the TEMPO styrene bond at the chain's terminus.

This calibration remains appropriate for poly(n-butyl acrylate) samples as shown by the Mark-Houwink-Sakurada parameters which are similar for n-butyl acrylate and styrene, (a) Couvreur, L.; Lefay, C.; Belleney, J.; Charleux, B.; Guerret, O.; Magnet, S. Macromolecules 2003, 36, 8260-8267.

In all our polymerizations of n-butyl acrylate mediated with TEMPO in the presence of ascorbic acid or with the acyclic nitroxide (ref 4, structure 2) reported by Hawker et al.,9 the PDIs of the resulting polymer were typically between 1.3 and 1.4.
