    摘要： The invention relates to a microcapsule preparation containing microcapsules having a core made from a hydrophobic material and a capsule coating made from a polymer which in a polymerized form contains at least 1 wt. % cationogenic monomers and/or multi-ethylenically unsaturated monomers whose unsaturated points are linked by means of successive chemical bonds, whereby at least one bond can be hydrolyzed by acid. The invention also relates to a microcapsule preparation containing microcapsules having a core which is made of a hydrophobic material comprising at least one olfactory agent or fragrant agent, and a capsule coating made from a polymer which in a polymerized form contains at least 1 wt. % anionogenic monoethylencially unsaturated monomers and/or multi-ethylenically unsaturated monomers whose unsaturated points are linked by means of successive chemical bonds, whereby at least one bond can be basically hydrolyzed. The microcapsules can be used in detergent or cleaning agents.

    摘要： The invention relates to the use of aqueous microcapsule dispersions as heat transfer liquids, the capsule cores of said dispersions consisting of latent heat storage materials and the shells consisting of a polymer. The inventive dispersions can be obtained by heating an oil-in-water emulsion containing monomers, radical starters and latent heat storage materials as dispersed phases. Said monomer mixture contains: between 30 and 100 wt. %, in relation to the total weight of monomers, of at least one monomer I selected from the Cl-C24 alkyl esters of acrylic acid and methacrylic acid, methacrylic acid and methacrylic nitrile; between 0 and 80 wt. %, in relation to the total weight of the monomers, of a bifunctional or polyfunctional monomer II which is insoluble or poorly soluble in water; and between 0 and 40 wt. %, in relation to the total weight of the monomers, of other monomers III.

    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： In a process for producing a particulate polymer P with a mean particle diameter d50 from 0.1 to 50 νm, an emulsion E is produced from one or more monomers M which can be polymerised into the polymer P by radical polymerisation, water and at least one protective colloid SK under high shearing forces, and the emulsion E is polymerised in a reactor by using a radical polymerisation initiator RI. The process is characterised in that maximum 75 wt % of the emulsion E ('initial proportion of E') are initially fed into the reactor before polymerisation begins, and in that at least 25 wt % of the emulsion E ('added proportion of E') are only fed into the reactor after the polymerisation begins.
