| Outline of Final Research Achievements |
Molecular mechanism of poly(methyl methacrylate) (PMMA) stereocomplexation is still not well-understood. In this work, we tried to observe the stereocomplexation process from isolated chains by atomic force microscopy. We solubilized a small amount of stereoregular PMMAs in a matrix monolayer as isolated chains, then, compressed the mixed monolayer to form stereocomplex. We successfully observed stereocomplexes composed of a few PMMA chains, in which only a part of it- and st-PMMA chains gathered and formed a stereocomplex with the residual chains emanated from it. We believe that further detailed study will improve our understanding of molecular mechanism of PMMA stereocomplexation.
