Abstract
<B>"PROCESSO DE FORMAçãO DE UMA MEMBRANA MICROPOROSA; MéTODO DE FABRICAçãO DA MESMA E APARELHO PARA SUA FORMAçãO"<D> Revela-se um processo para produzir uma membrana microporosa geometricamente simétrica, contínua, reforçada e com três zonas, incluindo um material de suporte poroso encapsulado dentro de uma zona do meio disposta entre uma zona superior e uma zona inferior, onde pelo menos uma das três zonas possui um tamanho de poro pelo menos cerca de vinte porcento (20%) maior que o tamanho de poro das outras duas zonas. São também revelados um aparelho para fabricar uma membrana microporosa, geometricamente simétrica, contínua, reforçada e com três zonas, e a membrana fabricada.
