Porous non-friable polymer film

   
   

Porous films are provided which include a blend of a film forming polymer and a non-film forming material, the film having a network of pores or channels throughout the film. The porous polymer films are formed between 0.degree. and 80.degree. C. retain porosity at elevated temperatures and are non-friable. A process for preparing porous polymer films and their applications are disclosed.

Пористые пленки обеспечены вклюают бленду пленки формируя полимер и нон-plenki формируя материал, пленку имея сеть пор или каналов повсеместно в пленка. Пористые пленки полимера сформированы между 0.degree. и 80.degree. C сохраняет пористость на повышенных температурах и нон-sypuce. Показаны процесс для подготовлять пористые пленки полимера и их применения.
