    摘要: Disclosed is a vapor permeable composition comprising a copolymer comprising copolymerized units of ethylene and copolymerized units of a comonomer providing an amine-reactive site; a short chain polymer having one primary amine active amine site, and comprising propylene oxide, ethylene oxide, or mixture thereof. The composition is useful as a vapor barrier for moisture control of buildings. Also disclosed are articles comprising the vapor permeable composition and methods of their use.
