Outline of Final Research Achievements

In this study, synthetic approach to polymer material with spider-silk motif was investigated. By using chain growth polycondensation of N-phenoxycarbonyl α－amino acid from amine-containing poly(propylene glycol) or poly(butadiene)as macroinitiator, various kinds of polypeptide chains was introduced to give a desired polypeptide-based materials. Clarifying the relationship between the chemical structure of the introduced polypeptide chain and the mechanical strength of the polymer, useful knowledge for designing polypeptide material was obtained.
Furthermore, the synthesis of new N-phenoxycarbonyl derivatives α－amino acid having reactive side chain was investigated. The polycondensation of these compounds provided easily a chemically modifiable unit, contributing to the further functionalization of the polymers material.
