TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The solid polymer electrolyte contains at least one metal salt, preferably a lithium salt comprising lithium hexafluorophosphate, lithium tetrafluoroborate, lithium perchlorate, lithium trifluoromethylsulfonate, lithium 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate, lithium trifluoromethanesulfonylimide and/or lithium bisoxalatoborate. The amount of metal salt is 0.001-30 (preferably 0.1-10) wt.%. The electrical component is in the form of a battery, where the electrodes are metal electrodes, preferably lithium electrodes, which are coated with the solid polymer electrolyte with a layer thickness of 1-10000 (preferably 20-500) mu m.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The reaction is added with at least one thermal initiator and/or at least one photoinitiator. Preferred Components: The weight ratio of the sum of repeating units (a) to the sum of the repeating units (b) is 1000:1-1:1000, preferably 2:1-1:2. The weight ratio of the sum of units (IV) to the sum of the units (V) and/or (VI) is 1000:1-1:1000, preferably 2:1-1:2. Preferred Definitions:    A1 = -(CH2-CH2-O-C(=O)-NH-CH2-CH2-CH2)-, -(CH2-CH2)- or (CH2-CH2-O)n1-;    D1 = (CH2-CH2-O)n1-, -(CH2-CH2-O-C(=O)-O-C(=O)-CH2-CH2-C(=O)-O-CH2-CH2)- or -(CH2-CH2-O-C(=O)-CH2-C(=O)-O-CH2-CH2)-;    n1 = 1-1000, preferably 1-10;    B1 = monovalent cationic radical of formula (b1)-(b5), (-N+((R2)3))X-, (-P+((R2)3))X- or (-S+((R2)2))X-;    R2 = linear or branched 1-12C-alkyl; and    X- = counter ion comprising F-, Cl-, Br-, I-, BF4-, PF6-, CF3SO3-, CF3(CF2)3SO3-, (CF3SO3)2N-, SCN-, (NC)2N-, trifluoroacetate, p-toluene sulfonate or R2O-SO3-.    EXAMPLE - 2-Methyl-acrylic acid-2-(3-chlorocabamoyloxy)-ethylester (3,01 mmole) was dissolved in chloroform and mixed with 1-methylimidazole (3.15 mmole) and further stirred at 70 degrees C for 24 hours under argon atmosphere. Then potassium hexafluorophosphate (3.04 mmole) in methanol was added and stirred for 24 hours at room temperature. The obtained precipitate was filtered and the solution was concentrated. The obtained solution was purified and the solvent was removed and dried to obtain 1-methyl-3-(3-2-(2-methylacryloyloxy)-ethoxycarbonylaminol-propyl)-3H-imidazol-1-ium-hexafluorophosphate (890 mg, 66.9%) as a yellowish oil.
