An electrode structure and its method of manufacture are disclosed. The disclosed electrode structures may be manufactured by depositing a first release layer on a first carrier substrate. A first protective layer may be deposited on a surface of the first release layer and a first electroactive material layer may then be deposited on the first protective layer.

Process for inhibiting the undesired free-radical polymerization of acrylic acid present in a liquid phase P, wherein the acrylic acid content of P is at least 10% by weight, the liquid phase P comprises in the range from 25 to 1000 ppmw of glyoxal based on the weight of the acrylic acid present in P and the liquid phase P is admixed with furfural in an amount that results in a furfural content in the range from 25 to 1000 ppmw based on the weight of the acrylic acid present in P. Liquid phase P, wherein the acrylic acid content of P is at least 10% by weight and the liquid phase P comprises in the range from 25 to 1000 ppmw of glyoxal and in the range from 25 to 1000 ppmw of furfural in each case based on the weight of the acrylic acid present in P.

Membrane comprising a block copolymer comprising polyarylene ether blocks and polyalkylene oxide blocks, wherein said polyalkylene oxide blocks comprise at least one polyethylene oxide segment and at least one segment of at least one polyalkylene oxide that is different from polyethylene oxide.

Polymers for membranes

Polyethers (A), whose main chain essentially consists of repeating units of the formulae (1) and (2) in alternating order, are useful as an additive to a porous polymer membrane, or as the main polymer constituent of a porous polymer membrane, for stabilizing said membrane against detrimental effects of oxidizing agents and/or for improving the stability of a filtration module comprising said membrane against detrimental effects of oxidizing agents. 

Improving the chemical stability of filtration membranes

Process for making a membrane M comprising the following steps: a) preparing a copolymer C, wherein said copolymer C comprises blocks of at least one polyarylene ether A and blocks of polyalkylene oxide PAO, wherein the content of polyethyleneoxide in copolymer C is 30 to 90% by weight and wherein copolymer C is prepared in a solvent L to yield solution S; b) providing a dope solution D comprising at least one polymer P; c) mixing solution S and dope solution D; d) preparing a membrane by bringing the mixture of solution S and dope solution D into contact with at least one coagulating agent.
