Abstract:
1. A solid polymer electrolyte or gel electrolyte polymer comprising an ion conductive polymer grafted or crosslinked comprising in the backbone of the polymer one or more moieties selected from wherein * designates connection to the rest of polymer backbone which is anhydride copolymer, G is H, C A, A′ and A″ are independently of the others C each of x, y and z is a number from 0 to about 125, and at least one of x, y or z is 1 or higher, E is H, C R′ is H or C R″ is H, C wherein each E′ is independently H, C or one E′ is H, C or the two E′ groups together form a maleimide group which is fused to the same polymer backbone or to the backbone of another polymer chain which comprises in the backbone of the polymer chain one or more moieties of Formula I or Formula II and thus forming a crosslink, wherein—formula I and II are obtainable by reacting a maleic anhydride copolymer with at least one amine of the formula and the maleic anhydride copolymer is a maleic anhydride copolymer with styrene.
