Abstract
Two kinds of organophosphorous-functionalized ionic liquid (ILs) were synthesized and confirmed by FT-IR, HRMS and NMR. The ionic liquids have good thermostability and the viscosity decrease with the increasing temperature. They were used as plasticizer for PMMA by melt blending. The glass transition temperature (Tg) and melt viscosity of the plasticized PMMA samples were determined by DSC and capillary rheometer, and the results show significantly decrease of the Tg and melt viscosity of samples with the increasing content of IL1 and IL2 from 5 to 20 wt%, and the plasticized PMMA systems show good thermal stability as well, indicating good miscibility and plasticization effect of the organophosphorous ionic liquids with PMMA .
