The Effect of the N-Substituent s-trans to the Carbonyl Group of N-Methylacrylamide Derivatives on the Stereospecificity of Radical Polymerizations

Radical polymerization of N-methylacrylamide (NMAAm), N,N-dimethylacrylamide (DMAAm), and N-methyl-N-phenylacrylamide (MPhAAm) was investigated in toluene at low temperatures. Atactic, isotactic, and syndiotactic polymers were obtained by the polymerization of NMAAm, DMAAm, and MPhAAm, respectively, indicating that the stereospecificity of the radical polymerization of acrylamide derivatives depended on the N-substituents of the monomer used. From the viewpoint of monomer structure, the origin of the stereospecificity of radical polymerization of NMAAm derivatives is discussed.
