Ionic liquid [bmim]PF₆(1-butyl-3-methylimidazolium hexafluorophosphate) was synthesized andcharacterized.It was used as a plasticizer for poly(methyl methacrylate) by means of in situ radical polymerization.The glass transition temperature and the thermal stability of the PMMA samples were determined byvirtue of DSC and TG.The glass transition temperature of the polymers displayed an almost linear decrease from 105℃ to belowroom temperature (20℃) with the increase of the ionic liquid content from 0 to 60%(volume fraction),and the corresponding mass loss of PMMAdecreased from 4.19% to 0.16%.All of theseindicated that the [bmim]PF₆as a plasticizer was able to reduce the glass transition temperature of PMMA and improved its thermal stability remarkably.
