| Outline of Final Research Achievements |
Polymerization of L-alanine ethyl ester hydrochloride in the presence of cellulose nanocrystal (CNC) prepared by treatment of cellulose sources with hydrochloric acid was investigated. Alanine oligomer products, such as alanine dimer and trimer, were successfully detected by a liquid chromatography-mass spectrometer, suggesting the potential of CNC as a polymerization catalyst. The product amounts were maximal at ambient temperature under weakly acidic or neutral conditions. When several amino acid monomers were applied, CNC accelerated specifically the polymerization of hydrophobic amino acid monomers. Unfortunately, the conversions of monomers to oligomers were less than several %, which should be improved in the near future.
