Abstract:
The invention relates to stabilisers containing at least two phenolic groups which are connected by a polyol, with a number average molecular weight of 75xF g/mol to 250xF g/mol, preferably 100xF g/mol to 200xF g/mol, in particular 100xF g/mol to 150xF g/mol, where the term F = the number of phenolic groups in the molecule, as bridging unit (II).
Abstract:
The invention relates to a method for production of xenon from gas mixtures, containing xenon and krypton as main components, whereby the gas mixture is brought into contact with a porous organometallic framework material and xenon is subsequently obtained by desorption.
Abstract:
The invention relates to nanoparticles, comprising a support and a coating of a polymer material. The polymer material comprises functional groups, to which reversible metal ions are bonded. Said nanoparticles may be incorporated in plastics and workpieces may be produced from the obtained compounds, which are particularly suitable for medical applications. The workpieces for example, drainage tubes, or inner coatings of medical devices, give off small amounts of metal ions in contact with body fluids which have an anti-microbial or bacteriostatic effect. On longer application the penetration of disease-inducing agents is effectively suppressed.
Abstract:

Abstract:
The invention relates to novel oil-in-water dispersions containing: a) at least one oxygen-containing organic substance, which is insoluble in water and solid at room temperature, and; b) at least one amide compound of general formula (I), wherein the variables R, R1, R2, A, B, X and Z have the meanings as cited in the description and in the claims. The invention also relates to the use of the inventive dispersions as a defoaming agent and/or deaerating agent in aqueous systems that tend to foam.
