Abstract
The disclosure provides a laminated polyolefin microporous membrane having propylene-α-olefin copolymer and methods of producing the same. The laminated polyolefin microporous membrane has a two-type three layer structure in which first polyolefin microporous layers are surface layers and a second polyolefin microporous layer is an intermediate layer which is different from the first polyolefin microporous layer.
