    摘要： The invention relates to a method for producing thermotropic (mono) films or composite films that contain at least one thermotropic layer that consists of a) 5 to 95 weight percent of a polymer as the component A, and b) 5 to 95 weight percent of a polymer as the component B that is different from A. A molecular mixture of components A and B has a cloud point below which the mixture is monophase and transparent and above which the mixture segregates into the components A and B. The components A and/or B may contain up to 15 mole percent of photoinitiator comonomers polymerized into the component. The layer contains optionally further components and optionally a support layer and/or a cover layer and optionally additional intermediate layers. The inventive method comprises the following steps: i) producing an intimate mixture that contains 10 to 98 weight percent of a mixture of components A, B and optionally further components and 2 to 90 weight percent of a solvent in which the components A and B are soluble, ii) removing the solvent, whereby an intimate polymer mixture from the components A and B and optionally further components is produced, iii) melting the intimate polymer mixture from step (ii) during or after the removal of the solvent, iv) optionally adding further components at a random point in time, v) shaping the mixture from components A, B and optionally further components to give a thermotropic (mono) film or, together with the support film and/or the cover layer and optionally the additional intermediate layers, to give a thermotropic composite film, and vi) optionally cross-linking said thermotropic film or said thermotropic composite film by UV radiation.

    摘要： The invention relates to the application of microcapsules I with one or more lipophilic substances as core material. Said lipophilic substances have a solid/liquid phase transition at a temperature ranging from -20 to 120 °C and a polymer which is used as a shell and can be obtained by means of radical polymerization of a monomer mixture containing 30 to 100 wt.%, referring to the total weight of the monomers, one or more C1-C24-alkyl esters of the acrylic acid and/or methylacrylic acid (monomer I), 0 to 80 wt.%, referring to the total weight of the monomers, one bi- or polyfuntional monomer (monomer II) which is insoluble or poorly soluble in water, and 0 to 40 wt.%, referring to the total weight of the monomers, and other monomers (monomer III). The microcapsules can be used as latent heat accumulators. The invention also relates to novel microcapsules Ia, spray-dried microcapsules Ia', methods for the production thereof, and to shaped bodies and coating masses containing said microcapsules.

    摘要： The invention relates to a method for surface-coating apparatuses and parts of apparatuses for the construction of chemical installations, for example apparatus, container and reactor walls, discharging devices, fittings, pumps, filters, compressors, centrifuges, columns, heat exchangers, dryers, reducing machines, built-in parts, packing and mixing mechanisms. The method is characterised in that bumps with an average height of 100 nm to 50 νm are produced on the surface to be coated, at average intervals of 100 nm to 100 νm, before the surface is coated by currentlessly depositing a layer of metal or a layer of a metal-polymer-dispersion using a galvanisation bath containing a metal electrolyte, a reduction agent and optionally, a polymer or polymer mixture to be deposited, in dispersed form.
