Beschreibung
Zusammenfassung:	Disclosed is a selectively permeable protective structure, a method for providing personal protection from exposure to harmful chemical and biological agents using an article that provides a barrier to such agents and a method for limiting damage to the article due to corrosion or mold growth, comprising wrapping or covering the article in the selectively permeable protective structure. The selectively permeable structure comprises a membrane comprising a copolymer comprising copolymerized units of ethylene and copolymerized units of a comonomer providing an amine-reactive site combined with a short chain polymer having from about 5 to 50 repeat units and containing one primary amine active amine site, having a moisture vapor permeation value of at least 200 g-mil/m2/24 h and barrier to liquid water, and optionally a supporting substrate.
