| Outline of Final Research Achievements |
Major component of chicken feather is keratin protein. Two sulfur atoms are crosslinked each other in keratin. Ionic liquid with sodium sulfite can completely dissolve feather keratin. Keratin composite is prepared by polymerization of acrylic monomer initiated from sulfur atom of keratin. 3 kinds of polymerization were used for preparation of keratin composite. When not only sulfur but also oxygen was used for the initiation of polymerization, density of acrylic graft became higher. The glass transition temperature for grafted acrylic polymer was enhanced by high graft density.
