Development of degradation and functional technique of cellulose with low environmental burden

在本研究中，我们研究了纤维素的降解和表面改性的机械化学反应。纤维素的机械化学降解从分子水平的表面开始进行。然后，纤维素与甲基丙烯酸2-羟乙酯（HEMA）在真空管中进行机械化学反应，制得纤维素-聚嵌段共聚物（HEMA）。此外，在真空条件下，苯纤维素与HEMA在管内进行机械化学反应也可生成嵌段共聚物，但HEMA的聚合性与纤维素不同。

In this study, we investigated the degradation and surface modification of cellulose using mechano-chemical reaction. The mechano-chemically degradation of cellulose proceeded from the surface at the molecular level. Next, mechano-chemical reaction of cellulose and 2-hydroxyethyl methacrylate (HEMA) in a tube under vacuum showed the production of block copolymer of cellulose-block-poly(HEMA). Furthermore mechano-chemical reaction of benzyl cellulose and HEMA in a tube under vacuum also produced the block copolymer, whereas the tacticity of HEMA polymerized varied as compared with the case of cellulose.
