摘要：
A process for producing a porous film containing a liquid-crystalline polyester, characterized by comprising the following steps (a), (b), and (c) in this order. (a) 100 Parts by weight of a liquid-crystalline polyester is dissolved in a solvent, and 1-1,500 parts by weight of a filler is dispersed in the solution to prepare a slurry coating fluid. (b) The coating fluid is applied to at least one side of a substrate to form a coating film. (c) The coating film is subjected to solvent removal, immersion in a solvent in which the liquid-crystalline polyester does not dissolve, and drying to thereby obtain a porous film containing the liquid-crystalline polyester.
摘要（中）：
一种制造含有液晶聚酯的多孔膜的方法，其特征在于包括以下步骤（a），（b）和（c））。 （a）将100重量份的液晶聚酯溶解在溶剂中，并将1-1,500重量份的填料分散在溶液中以制备浆料涂布液。 （b）将涂布液施加到基材的至少一侧以形成涂膜。 （c）将涂膜进行溶剂除去，浸渍在不溶于液晶聚酯的溶剂中，干燥，得到含有液晶聚酯的多孔膜。
