Excluding chloroform, which solvent would be suitable to dissolve PMMA while preserving its optical properties such as transparency, and which solvent would provide fast solvent removal? Could you provide a recommendation?
Tetrahydrofurane works well as a solvent for PMMA. In our group we use it as a solvent in which we synthesize PMMA and also as an eluent in the size exclusion chromatography setup, which we use to determine the polymers' molecular weights and dispersities. The boiling point at 66°C makes a removal of the solvent quite easy, too.
Another solvent, which is even easier to remove might be dichloromethane, which has a boiling point slightly below 40°C.
