1. A composition, comprising a multi-layer halogenated polyolefin microporous membrane, comprising:
a filtration layer; and a support layer, the microporous membrane being non-dewetting and contact wettable with a solution of 94 weight percent or less of methanol in water; having a strength of greater than 16 Newtons and a thickness of less than about 30 microns; including one or more surfaces with an O/C ratio of greater than about 0.06; and having an LRV of at least 3 for 0.1 micron or smaller particles in water. |
