Abstract: Electrode materials suitable for electrochemical cells containing a) a polymeric binder which is composed essentially of polyisobutene having a limiting viscosity number of from 551 to 661 g/cm.sup.3 and b) a solid which is capable of reversibly taking up or releasing lithium ions in an electrochemical reaction.

Abstract: Curable coating agents, a process for the production of scratch-resistant coatings on plastics, and articles coated by this process.The coating agents are polycondensates ofa reaction product, containing two or more carbon-carbon double bonds and one or more hydroxyl or alkoxy groups per molecule, obtained from an olefinically unsaturated silane containing 2 or more hydroxyl or alkoxy groups, whose olefinically unsaturated organic radical is bonded via a C-Si bond, and a hydroxyl-containing .alpha., .beta.-olefinically unsaturated monomer,an olefinically unsaturated silane of the general formulaR.sup.1 --Si(OR.sup.2).sub.3where R.sup.1 is a vinyl radical or an alkyl acrylate or alkyl methacrylate radical bonded to the Si atom via a C--Si bond and R.sup.2 is hydrogen or a saturated hydrocarbon radical, anda saturated silane of the general formula ##STR1## where R.sup.3 and R.sup.
