Abstract

The absorption of several solvents including methylene chloride (MC), methyl chloroform (MCF), gamma-butyrolactone (BLO), dibromomethane (DBRO), 1,2-dichloroethane (DCE), and 1,2-dichloropropane (DCP) in Kapton H*, Upilex S**, and Upilex R** polyimide film was measured gravimetrically. A significant difference in the rate and amount of absorption of these chemicals by the various films was observed. Complimentary Rutherford Backscattering Spectrometry (RBS) measurements provided additional information regarding the amount of solvent absorbed and mode of transport.
