The strong Brønsted acid‐promoted group transfer polymerization (GTP) of N,N‐dimethylacrylamide (DMAA) using trifluoromethanesulfonimide (Tf2NH) and 2,3,4,5,6‐pentafluorophenyl‐1,1‐bis(trifluoromethanesulfonyl)methane (Tf2CHC6F5) was carried out to quantitatively evaluate the effect of the counter a...
