【摘要】 <正> 离子液体作为绿色溶剂之一是当今绿色化学研究的热点。离子液体具有无毒、不可燃、蒸汽压接近于0、稳定性好等特点,广泛应用于电化学、化工分离、有机合成以及材料制备等方面的研究和开发。离子液体在聚合反应中的应用研究涉及到聚合反应的各个领域,1984年Pickup等首次以离子液体为溶剂用电化学方法成功合成了聚吡咯,二十更多还原

【Abstract】 Ionic liquids are prospective environmentally friendly reaction media for a variety of chemical reactions. In this paper, the radical copolymerization of acrylonitrile (AN) with methylate (MA) in ionic liquid with AIBN as initiator was investigated. It is found that the average molecular weight increased as AN increasing, while the conversation had a maximum value. From the element analysis, the reactivity ratios were calculated respectively as rAN=0.3562 and rMA=0.6843 at 70℃. The co-polymerization rate of AN and MA has been studied using expansion meter. When the concentration of initiator and monomers and the reaction temperature increased, the co-polymerization rate increased. The co-polymerization rate equation of the system was Rp=k CAIBN.27 CAN-MA1.81and the reaction activity energy was 50.9kJ/mol kJ·mol-1.更多还原
