标题 :Synthesis and polymerization of vinyl triazolium ionic liquids
发明人:LUEBKE DAVID; NULWALA HUNAID; MATYJASZEWSKI KRZYSZTOF; ADZIMA BRIAN
权利人:US ENERGY; THE US DEPARTMENT OF ENERGY
摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.
