Abstract
Water transport through and sorption in films of polyimide-polysiloxane block copolymers were studied at 25 °C and atmospheric pressure. The permeability and diffusion coefficients and, to a certain extent, also the sorbed amount were found to depend on the content of the polysiloxane blocks.
