Research Abstract

The final objective of this study is to expand the utilization of cellulose, which is one of the main compounds ascarbon resource in the earth. For that, I tried to synthesize a linier block co-polymer with cellulose and a hydrophobic/hydrophilic polymer. The co-polymer is expected to dissolve in water or oil and to exhibit molecular orientation although cellulose itself is not. This study established the preparations for glucose whose hydroxyl groups except the first position were protected and for glucose with methoxy polyethylene glycol at the first position.
