Abstract

"PROCESSO PARA PRODUZIR UMA MEMBRANA HIDROFóBICA INTEGRALMENTE ASSIMéTRICA MEMBRANA HIDROFóBICA INTEGRALMENTE ASSIMéTRICA, E, USO DA MESMA". A invenção refere-se a um método para a produção de uma membrana poliolefinica hidrofóbica integralmente assimétrica com uma estrutura de suporte microporosa de poro aberto, esponjosa e uma camada de separação possuindo uma estrutura mais espessa por meio de um processo de separação de fases de líquido-líquido termalmente induzida. Uma solução de pelo menos uma poliolefina é extrusada para formar um corpo moldado. O solvente usado é tal que a temperatura de separação de uma solução a 25% em peso de poliolefina no citado solvente está entre 10<198>C e 70<198>C acima da temperatura de endurecimento. Após a desmoldagem, o corpo moldado é resfriado por um meio de resfriamento líquido que não dissolve o polímero em temperaturas de até a temperatura de ferramenta, até a separação de fases e o endurecimento da fase rica em polímero. A membrana integralmente assimétrica assim produzida possui uma porosidade que é maior do que 30% em volume - 75% em volume, uma estrutura de suporte microporosa de poro aberto, esponjosa destituída de macrovazios e possui poros isotrópicos em seu centro e pelo menos uma camada de separação possuindo um número máximo de poros > 100 arranjados sobre pelo menos uma sua superfície. A membrana e preferivelmente usada para processos de separação gasosa ou de transferência gasosa e especialmente para a oxigenação de sangue.
