Crosslinked polymers and their uses in electrochemical systems, for example, as electrolyte membrane, are described. More precisely, these crosslinked polymers are formed by the crosslinking of a random copolymer based on monomers of glycidyl methacrylate or acrylate and of poly(ethylene glycol) methyl acrylate or methacrylate with a volatile polyamine crosslinking agent.

Disclosed are ionomers of co-polymers of vinylidene substituted aromatic monomers and unsaturated compounds containing acid groups crosslinked by the residue of one or more metal salts and/or metal oxides of a metal having a valence of 2 or greater. The crosslinks are reversible and the weight average molecular weight of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids may be substantially the same after the crosslinking is reversed as it is before crosslinking. A portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids. Disclosed are methods of preparing such ionomers

A separator for at least one of electrochemical energy accumulators or converters includes: a porous substrate with a comb polymer, the comb polymer containing a polymer main chain along several lateral chains that are covalently bonded to the polymer main chain. At least one of the lateral chains has at least one Lewis-acid or Lewis-base functionality.

A terpolymer of ethylene, of 1,3-butadiene and of an aromatic α-monoolefin is provided. The terpolymer contains more than 60 mol %, preferably at least 70 mol %, and preferably at most 90 mol % of ethylene units, at most 10 mol % of aromatic α-monoolefin units and 1,2-cyclohexanediyl units.

Such a diene terpolymer rich in ethylene units has the advantage of exhibiting a reduced, or even zero, crystallinity.

The present specification relates to a battery, comprising an anode, a cathode, an electrolyte disposed between the anode and the cathode, a halogen in contact with the cathode, and a metal in contact with the anode, wherein the halogen is in contact with a polymeric halogen sequestering agent (HSA) which is a polymer comprising a moiety capable of sequestering the halogen.

Disclosed are a sealing material for solar cell modules and a manufacturing method thereof capable of endowing good transparency and heat resistance to the sealing material for solar cell modules while using a polyethylene-based resin.
