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

This is the authors' abstract. We don't add key points for this paper.

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).
