Abstract: Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.

Abstract: A composition including a polymeric binder for the negative electrode of a secondary energy storage device is provided. The polymeric binder provides a matrix for particulate electrode-forming materials, which may include an active material and a conductive material. The polymeric binder contains acid functional groups. The polymeric binder also contains other functional monomers, which also may contribute to the performance of the polymeric binder in the negative electrode.

Abstract: An electrode forming composition for use as the active material layer on a current collector of an electrode within a non-aqueous electrical energy storage device is provided. The electrode forming composition includes a) at least one particulate electrode-forming material, b) a polymeric binder. The polymeric binger includes at least one non-ionic monoethylenically unsaturated monomer and at least one particular oxyalkylated monomer with ethylenic unsaturation and terminated by hydrogen or an aryl or alkyl chain.
