Abstract
A series of compatible blends of poly(methyl methacrylate) with an ionic liquid(IL),1-dodecyl-3-methylimidazolium hexafluorophosphate[C12MIM] [PF6],was prepared by melt blending.The blends were foamed with supercritical CO2 as the blowing agent via a rapid pressure-quenching process.By adding IL,the CO2 absorption of PMMA was increased,and the glass transition temperature was lowered.The effects of IL on the foaming behavior of PMMA depended on foaming conditions.When the foaming temperature and pressure were low,pure PMMA could not be foamed,while the addition of IL facilitated the formation of cells.On the other hand,pure PMMA could be foamed at higher temperatures and pressures,and adding IL further increased the cell size of the foamed samples;however,the cell size was still within the micron-meter scale and had a narrow distribution.
