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.
