Abstract

"COMPOSIçãO LìQUIDA". Composição fluida contendo copolímero de troca iónica, que é perfluoretada com grupos funcionais -SO~ 3~M, íons M-hidrogênio ou íons de metais alcalinos ( EM maior do que 900 ) e um solvente orgânico polar, ou uma mistura de um solvente orgânico polar e um solvente não polar e, como copolímero de troca iónica perfluoretado, a composição contém um copolímero de troca iónica perfluoretado tendo um grau de cristalinidade de 2 a 10% e uma razão entre a densidade do copolímero de troca iónica indicado e a densidade do copolímero perfluoretado original em forma não iónica entre 0,9 e 0,97. A proporção dos componentes é em % em peso: copolímero de troca iónica perfluoretado 1 a 35; solvente orgânico polar ou mistura de solvente orgânico polar com solvente não polar 65 a 99. Tais composições são usadas na produção e reparo de membranas de troca iónica ( IEM ) usadas na eletrólise alcalina com cloro ou na eletrólise com água em células de separação combustível/gás.
