Beschreibung
Zusammenfassung:	Microporous materials and articles are disclosed. The microporous materials contain a crystallizable propylene-containing polymer, a beta-nucleating agent, and a diluent that is miscible with the polymer at a temperature above the melting temperature of the polymer and that phase separates from the polymer at a temperature below the polymer crystallization temperature. The invention is also directed to methods of forming the microporous material using thermal induced phase separation and subsequent processing.
