  公开号：EP0683196A2

  公开（公告）日：1995-11-22

  A porous biaxially oriented film comprising an ethylene/a-olefin copolymer wherein the copolymer is obtained by copolymerising an ethylene and an a-olefin having 4 to 8 carbon atoms, wherein the a-olefin is present in an amount of from 1.0 to 7.5 per 100 carbon atoms of the copolymer and the intrinsic viscosity [η] of the copolymer is from 3.5 to 10.0 dl/g ; wherein (i) the film has a microporous structure in which microfibrils of the ethylene/a-olefin copolymer are uniformly dispersed ; (ii) when cooled to room temperature after heat-treatment at 160°C in a constrained state the film loses its air permeating property due to the loss of porosity but still retains the structure which is based on the microfibrils ; (ii) at a temperature of not less than 170°C the film breaks up after having lost the gas permeating property.

  一种包含乙烯/a-烯烃共聚物的多孔双向拉伸薄膜，其中共聚物由乙烯和具有 4 至 8 个碳原子的 a-烯烃共聚得到，a-烯烃的含量为每 100 个共聚物碳原子 1.0 至 7.5 个，共聚物的固有粘度[η]为 3.5 至 10.0 dl/g； 其中 (i) 薄膜具有微孔结构，其中乙烯/a-烯烃共聚物的微纤维均匀分布； (ii) 在 160°C 的热处理后，在受限状态下冷却至室温，薄膜因失去孔隙率而失去透气性能，但仍保留以微细纤维为基础的结构； (iii) 在 160°C 的热处理后，在受限状态下冷却至室温，薄膜因失去孔隙率而失去透气性能，但仍保留以微细纤维为基础的结构； (ii) 在不低于 170°C 的温度下，薄膜在失去透气性能后破裂。
