| 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.

| Abstract: | 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 BMIMCl w... |
