| Outline of Final Research Achievements |
Physical properties of cellulosic materials are affected by hydrogen bonding formed in the noncrystalline regions contained in the materials. There is less information on the noncrystalline regions of cellulose because of the limited number of analytical methods for the noncrystalline regions due to the complicated formation of hydrogen bonding. In this study, 2 kinds of regioselectively methylated cellulose derivatives, 2,3-di-O-methylcellulose (23MC) and 6-O-methylcellulose (6MC) were employed as samples since both of them are supposed to have restricted formation of hydrogen bonding, respectively. Films prepared from 23MC or 6MC were analyzed using the combination of vapor-phase deuteration, FTIR spectroscopic measurements and a kinetic analysis, which provided molecular assembly states in each noncrystalline region. Moreover, the hydrogen bonds contained in each noncrystalline region were detected and assigned using generalized two-dimensional correlation IR analysis.
