A method of making a crosslinked polymer is provided as well as the polymer so made, the method comprising the steps of: providing a highly fluorinated fluoropolymer, typically a perfluorinated fluoropolymer, comprising pendent groups which include a group according to the formula -S02X, where X is F, Cl, Br, OH, or O-M+, where M+ is a monovalent cation, and exposing said fluoropolymer to electron beam radiation so as to result in the formation of crosslinks. Typically, the method according to the present invention additionally comprises the step of: forming said fluoropolymer into a membrane, typically having a thickness of 90 microns or less, more typically 60 microns or less, and most typically 30 microns or less.
L'invention concerne un procédé permettant de produire un polymère réticulé ainsi que le polymère obtenu. Ledit procédé consiste: à fournir un fluoropolymère à fluoration élevée, en général un fluoropolymère perfluoré, comprenant des groupes pendants qui incluent un groupe représenté par la formule S0¿2?X, dans laquelle X représente F, Cl, Br, OH, ou O?-¿M?+¿, M?+¿ étant un cation monovalent; et à exposer ledit fluoropolymère à un rayonnement de faisceau électronique afin de former des réticulations. En général, le procédé de l'invention consiste également: à former ledit fluoropolymère dans une membrane dont l'épaisseur est généralement de 90 microns ou moins, de préférence 60 microns ou moins et idéalement 30 microns ou moins.
