| Outline of Final Research Achievements |
New synthetic methods for poly(amino acid)s, which have the potential as biomaterials, were investigated. In order to resolve the problems of the traditional and exclusive method essentially, the new cyclic monomer structure was designed and studied for the polymerization. The findings are as follows; 1) Polysarcosine was obtained by the radical polymerization using the UV irradiation or the nitroxy radical mediator; 2) The latter polymerization conditions produced the copolymers of sarcosine or alanine with methyl methacrylate; 3) The monomers having a free carboxy group were obtained from aspartic and glutamic acids and gave poly(amino acid)s with the aid of a base catalyst.
