Polymer phase diagram in ionic liquids — •Daniela Fell1,2 and Jochen S. Gutmann1,2 — 1University of Mainz, Germany — 2Max Planck Institute for Polymer Research, Mainz, Germany
We have developed a new, fast and simple method for recording polymer phase diagrams using a normal flatbed scanner. The synchronization of the scanner and a temperature control unit allows us to automatically heat our setup in well-defined steps and then automatically scan. In one measurement series we are able to examine up to 80 different polymer concentrations. With this setup we are detecting the change of the cloudiness of a polymer in an ionic liquid. The obtained pictures are automatically analysed and the results are transferred to a single phase diagram.
With the help of this fast and automated method we have recorded phase diagrams of polymethylmethacrylate (PMMA) of different molecular weights in the room-temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]).
