ABSTRACT:
The present application relates to enclosure members consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and having a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet solvents and fuels of less than 1/7, optionally less than 1/40 of the permeability of untreated enclosure members having a thickness of 1 mm. Said low permeability is due to the presence of a layer of an iron phenanthroline complex on at least the inner surface of said enclosure members, having a portion of the hydrogen atoms replaced by sulfonic acid or sulfonate groups.
