A membrane that includes: at least one layer comprising a first silane-crosslinked polyolefin elastomer having a density from about 0.80 g/cm3to about 1.75 g/cm3. The silane-crosslinked polyolefin elastomer can exhibit a crystallinity of from about 5% to about 25% and a glass transition temperature of from about −75° C. to about −25° C. Further, the first silane-crosslinked polyolefin elastomer can comprise a first polyolefin having a density less than 0.90 g/cm3, a second polyolefin, a silane crosslinker, a grafting initiator, and a condensation catalyst. In addition, the at least one layer can comprise a thickness from about 0.2 mm to about 3 mm. |
