中文摘要：
以离子液体为反应介质，氯乙酰氯为酰化试剂，在不加任何催化剂的条件下，一步法制备出纤维素氯乙酰酸酯。研究了反应条件（酰化试剂用量、反应时间、反应温度）对纤维素取代度（DS）的影响，并对产物结构进行表征（FT—IR、NMR）。随后以纤维素氯乙酰酸酯为大分子引发剂，引发了甲基丙烯酸甲酯（MMA）在离子液体中的原子转移自由基聚合（ATRP）。研究结果表明，MMA在离子液体中的聚合是活性／可控的。
英文摘要：
Cellulose chloroacetate （Cell-ClAc）, as a macroinitiator, was first synthesized by direct acylation of cellulose with chloroacetyl chloride without any catalyst under mild conditions in an ionic liquid, 1 - allyl - 3 - methylimidazolium chloride （BMIMCl）. Samples were analyzed by NMR and FT - IR. The effects on the DS of the cellulose of acylation reagent, reaction temperature and reaction time were studied. Then, the cellulose-based macroinitiator was used for the ATRP of MMA. The copolymerization was carried out in BMIMCI without homopolymer byproduct. And the result showed that the polymerization is controlled/living.
