Process for preparing a solid, polymeric electrolyte, in membrane from, characterized in that: (1) a mixture is prepared, which contains: (a) a vinyl ether (I) of formula R-(-O-CH2-CH2-)n-O-CH=CH2 wherein R=Me or Et and n is an integer comprised within the range of from 1 to 16; (b) a divinyl ether of formula CH2=CH-(-O-CH2-CH2-)m-O-CH=CH2 wherein m is integer comprised within the range of from 1 to 10, in a molar ratio to the vinyl ether (I) comprised within the range of from 2:98 to 60:40; (c) an ionic compound in an amount comprised within the range of from 1 to 30% by weight; (d) an oligomer or a dipolar aprotic liquid in an amount comprised within the range of from 0 to 80% by weight; (e) a photoinitiator in an amount comprised within the range of from 0 to 10% by weight; (2) the above mixture is applied onto an inert support and is exposed to a source of ultraviolet light, or to an electron beam. |
