Outline of Final Research Achievements

Polymer monolayers have been intensively studied, however, the chain packings in the monolayers, the most important point to understand them, are not well-understood. In this work, we studied mixed monolayers of poly(methyl methacrylate) (PMMA) with various poly(acrylate)s (PAs), and found the PMMA is miscible with the various PA monolayers. By solubilizing a small amount of PMMA in the PA monolayers, the PMMA chains solubilized in the monolayers could be directly visualized by atomic force microscopy. The radius of gyration of the PMMA were evaluated as a function of the molecular weight of the PMMA and the matrix PAs. The chain packings in the monolayers were discussed.
