Stereoregular polymerization within template nanospaces

Abstract

Highly efficient stereoregular polymerizations within template nanospaces using free radical initiators, based on stereocomplexes formed between isotactic and syndiotactic methacrylate polymers are reviewed. Ultrathin films composed of double-stranded helical or van der Waals contacted stereocomplex nanostructures were successfully prepared by the layer-by-layer assembly method, and fundamental aspects of film preparation were summarized. Template nanospaces were prepared by the selective solvent extraction of a single component from stereocomplex films composed of it-poly(methyl methacrylate) and st-poly(methacrylic acid), The resulting porous films with designed nanospaces were used for template polymerizations. Methacrylate polymers with high iso- and syndiotacticities were synthesized within nanospaces. Structural information not only of template stereoregularity but also of template chain length was efficiently transferred to synthesized polymers.
