<p>A single or multi-layer microporous material of which at least one layer contains a compatible, melt-processible polymer mixture having a first polymer component with a melting point greater than 140 °C and a second polymer component having a melting point lower than 120 °C is described as well as a method of preparing the material. The first polymer component and the second polymer component are miscible in a compound or compatible liquid when heated above the melting temperature of the first polymer component or above the liquid-liquid phase separation temperature and phase separate from the compound or compatible liquid when cooled. The materials are particularly useful as battery separators.</p> |
