摘要：Microporous materials and articles are disclosed. The microporous materialscontain a crystallizable propylene-containing polymer, a beta-nucleating agent, and adiluent that is miscible with the polymer at a temperature above the meltingtemperature of the polymer and that phase separates from the polymer at atemperature below the polymer crystallization temperature. The invention is alsodirected to methods of forming the microporous material using thermal induced phaseseparation and subsequent processing.
