Abstract

AbstractRadical polymerization of N‐methyl‐N‐(2‐pyridyl)acrylamide (MPyAAm) was carried out in dichloromethane at low temperatures in the presence of trifluoroacetic acid (TFA). The m dyad contents of the polymers obtained at 0 °C increased linearly from 37 to 60% with an increase in the [TFA]0/[MPyAAm]0 ratio from 1 to 5. Nuclear magnetic resonance (NMR) analysis of MPyAAm–TFA mixtures in dichloromethane‐d2 revealed that the favorable conformation in terms of the pyridyl group to the carbonyl group in MPyAAm switched from s‐trans to s‐cis by protonation. The results suggest that controlling the conformation of MPyAAm resulted in control of the stereospecificity in radical polymerization of the monomer. © 2011 Wiley Periodicals, Inc.
