Stereospecific Radical Polymerization of a Side‐Chain Transformable Bulky Acrylamide Monomer and Subsequent Post‐Polymerization Modification for Syntheses of Isotactic Polyacrylate and Polyacrylamide

N. Thus-obtained PMA showed higher isotacticity m=74 % than that directly obtained via radical polymerization of methyl acrylate (MA) (m=51 %). The isotacticity was further increased as the temperature and monomer concentration were lower, and eventually m was increased up to 93 %. The aminolysis PPM after the iso-specific radical polymerization of 1 gave various isotactic polyacrylamides carrying different alkyl pendant groups, including poly(N-isopropylacrylamide) (PNIPAM).
