Outline of Final Research Achievements

The interaction between polymers and small molecules was investigated in order to find a new identification method of various fibers/polymers. First, the adsorption of organic compounds such as methanol, acetonitrile, 1,4-dioxane, toluene, N,N-dimethylformamide, and p-xylene, etc. to various fibers such as cotton, rayon, polyester, and nylon, etc. was examined. Each fiber showed its own adsorption tendency. In addition, the adsorption of the compounds to synthetic poly(amino acid)s was examined. Although polyglycine showed a poor adsorption property, the adsorption amount of other polyaminoacids was increased with an increase in the C atom numbers in side chains of amino acid residues; the adsorption amount was increased in the order, poly(L-alanine) < poly(L-valine) < poly(L-leucine). A possibility of a new identification method of polymers was found out.
