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

在本研究中，我们利用机械力化学反应研究了纤维素的降解和表面改性。纤维素的机械力化学降解是在分子水平上从表面开始的。接下来，纤维素和甲基丙烯酸羟乙酯(HEMA)在真空下在管内发生机械力化学反应，生成了纤维素-嵌段-聚(HEMA)嵌段共聚物。此外，苄基纤维素和HEMA在真空下在管内的机械力化学反应也生成嵌段共聚物，而HEMA聚合的嵌段共聚物的规整性与纤维素相比有所不同。

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.
