## Abstract Three different supercritical fluids (SCF), CO~2~, dimethyl ether (DME), and propane, are investigated as potential solvents for processing two lactideβbased terpolymers and two perfluorocyclobutyl (PFCB) aryl ether polymers. The repeat unit of the lactideβbased terpolymers consists of
Polymer additives were extracted with supercritical carbon dioxide and collected in a microtrap. The collected samples were separated by microcolumn liquid chromatography. Polymer samples down to the sub-milligram level were handled without loss of extract. Information about the distribution of addi
