Abstract

"PPROCESSO PARA A PREPARAçãO DE UMA MEMBRANA HIDRóFOBA, MEMBRANA HIDRóFOBA, E, UTILIZAçãO DA MEMBRANA". Processo para a preparação de membranas poliolefínicas hidrófobas para a troca de gás mediante separação de fases líquido-líquido induzida termicamente. Uma solução de pelo menos uma poliolefina em um sistema de solvente com uma viscosidade menor que 60 mPa s, constituída de um composto A e um composto B, é extrudada e um corpo moldado. O composto A é solvente e o composto B, de preferência, não-solvente para o polímero, e a temperatura de ebulição do composto A é pelo menos 50°C maior do que aquela do composto B. Após deixar a tubeira, o corpo moldado é exposto, com pelo menos uma superfície, a uma atmosfera promovedora de evaporação do composto B e, em seguida, resfriado até a separação de fases e o enrijecimento da fase rica em polímero. A membrana integralmente assimétrica preparada desta forma apresenta uma porosidade maior que 50% em volume até 75% em volume, uma camada de suporte microporosa de poros abertos, parecida com uma esponja, sem macro-espaços, e com poros, em média, isotrópicos, e [apresenta] pelo menos uma camada de separação com. no máximo, poros < 100 nm. A membrana é utilizada, de preferência, para a oxigenação de sangue.
