The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof.

Process for the production of water and solvent-free nitrile rubbers

The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof. This process involves removing volatile compounds from a fluid (F) containing (1) at least one nitrile rubber and (2) at least one volatile compound, wherein the process comprises at least the steps of a.) treating the fluid (F) in at least one conversation unit, b.) retreating the concentrated fluid from step a.) in at least one retreating unit and c.) feeding the retreated concentrated fluid from step b.) into at least one retreating unit.

A multilayer oxygen consuming electrode having a side facing the oxygen-containing gas and a side facing the alkaline electrolyte, wherein the electrode includes at least one support, and at least two layers containing a catalyst and a hydrophobic material, wherein the outermost layer facing the gas side has a lower proportion of catalyst than the outermost layer facing the electrode side and wherein the proportion of hydrophobic material is not more than 8% by weight based on the total amount of the catalyst the hydrophobic material.

The present invention relates to the technical field of isocyanates. The present invention provides a method for preparing NCO prepolymers by reacting a stoichiometric excess of an organic isocyanate with an isocyanate-reactive component, the reaction components being mixed together and the mixture being introduced directly into a storage or transport vessel, where it reacts to completion.

Method for producing metal particles, metal particles produced thereby, and the use thereof

A method for producing gas diffusion electrodes, in particular for use in electrolysis cells, as well as electrodes and their uses are described. A method of the present invention involves first, a sheet-like structure is produced by means of a pair of rolls by rolling a powder mixture containing at least one catalyst or a catalyst mixture and a binder, and then the sheet-like structure is connected to an electrically conductive catalyst support by rolling by means of a pair of rolls. In one embodiment the clamping force of the rolls is preferably kept constant in the range from 0.2 kN/cm to 15 kN/cm.
