Abstract: The mixtures contain (a) at least one sterically hindered amine of the formula (I) in which R and R are H, methyl or phenyl, and a further component from the groups (b) UV absorbers and/or (c) antioxidants from the classes consisting of sterically hindered phenols, phosphites and/or vitamin E or derivatives thereof. The mixtures are distinguished by a good light-stabilisation action in polyurethanes.

Abstract: Use of compounds of the general formula (I) in which X, Y and R to R are as defined in Claim 1, for stabilising organic material, especially plastics and coatings and also oils, textiles and paper, and also as an antistatic, a plasticiser for antimicrobial finishing, an agent for eliminating interfering substances and a fixative (fixing agent) for anionic dyes.

Abstract: Polymers contain, as mesogenic groups, groups which produce a discotic phase, and furthermore can contain pleochroic dyes. The novel polymers possess novel properties, and combinations of properties, which the conventional polymers which form liquid-crystalline phases do not possess. The polymers can be used in electro-optical displays, in storage elements, as electrically or photo-electrically conductive polymers and as strain sensors.

Abstract: An optical recording medium contains, on a base, one or more dyes and a polymer which forms liquid-crystalline phases. The information is written into the uniformly oriented liquid-crystalline polymer layer, for example by means of a laser. During this procedure, the polymer heats up locally to above a phase transition temperature. By cooling, the resulting change is frozen in the glass state. The information can be erased by applying an electric field and/or heating. The recording material permits high-contrast storage and possesses high sensitivity, good resolution and excellent stability.

Abstract: Vinylglyoxal derivatives of the general formula I (I) where R is straight-chain or branched alkyl or alkenyl, cycloalkyl or unsubstituted or substituted phenyl, are prepared by a process in which bicyclo[2.2.1]hept-5-enecarbaldehyde of the formula V (V) is either (a) subjected to autocondensation with formation of a compound of the formula VII (VII) or (b) reacted with a compound of the general formula II R-CH=O (II) where R has the above meanings, with formation of a mixture of the compounds of the general formulae VIII (a) and (b) (VIIIa) (VIIIb) where R is as defined above, in the presence of a catalyst, and the compound of the formula VII or the compounds of the formulae VIII (a) and (b) is or are oxidized to the corresponding dicarbonyl compounds, after which gas-phase pyrolysis is carried out at from 500 DEG to 700 DEG C. and under reduced pressure, in particular less than 10-1 mbar, and, if desired, the resulting compound of the general formula I is further purified. These compounds can be used, for example, as monomer components in polymeric systems.

Abstract: Production of an electrically conductive surface layer on moulded articles consisting of plastics which are soluble or can be swelled in organic solvents, the conductivity of which surface layer is based on a system embedded therein of… - organic electron acceptors (I) on the one hand and… - organic electron donors (II), iodides (III) or mixtures of (II) and (III) as electron donors on the other hand,… in that the moulded articles are treated with organic solutions of these components. … The products of the process have a surface resistance between 10 and 10 ohms and have the advantage that the other characteristics of the moulded articles are virtually uninfluenced by the means (I) to (III).
