Abstract

The nitroxide-mediated polymerization of N-tert-butylacrylamide (TBAM) in DMF at 120 °C using SG1/DEPN and AIBN has been investigated. Linear growth in number-average molecular weight (M̄_n) versus conversion and narrow molecular weight distributions (MWDs) with high livingness were obtained up to ≈8000 g mol^-1. For higher molecular weights, the MWDs gradually became broader with low molecular weight tailing, and M̄_n. deviated downwards from theoretical values. Quantitative analyses of MWDs, along with specifically designed conventional radical polymerizations at 120 °C, were consistent with chain transfer to monomer limiting the attainable M̄_n. This finding can be equally applied to existing literature polymerizations of TBAM.
