Abstract: Quaternary ammonium compounds of the formula in which R1 denotes an alkyl or alkenyl radical with 12 to 22 carbon atoms; R2 and R3 are identical or different and denote an alkyl radical with 1 to 4 carbon atoms; x denotes an integral or non-integral number from 1 to 3; and A(-) denotes an alkyl- or alkenyl-sulfonate anion, an alkyl or alkenyl-carbonate anion or a benzoate, naphthoate or phenylsulfonate anion, the tosylate ion being excluded, a process for their preparation and their use as drag reducing agents in liquids with turbulent flow.

Abstract: - 45 - HOE 89/F 095 Liquid-crystalline mixtures in particular ferroelectric liquid-crystalline mixtures The novel liquid-crystalline mixtures (in the case of ferroelectric behavior they additionally contain an optically active compound as dope) are based on at least two mixture components of the general formula (I) and at least one carboxylate of the general formulae ¢sic! (II), (III) or (IV). (I) (II) X = O or a single bond (III) (IV) The mixtures have favorable properties for use in electrooptical display elements, such as high contrast, low melting point and short switching times.

Abstract: HOE 89/F 080 of the disclosure Optically active dioxolanylacrylates and dioxolanylpropionates carrying a mesogenic radical, a process for their preparation, and their use as dopes in liquidcrystal mixtures. Optically active 1,3-dioxolane derivatives, carrying a mesogenic radical, of the general formula (I) (I) are suitable as dopes in - in particular ferroelectric liquid-crystal mixtures. The symbols in the general formula have the following meaning here: R1 is constructed analogously to the moiety of the general formula on the right of X or is an alkyl or alkylene ¢sic! radical which may be substituted, R2, R3 and R4 are H or alkyl (R4 is alternatively alkenyl), which may also be substituted ¢R2 and R3, together with the C(2) of the dioxolane ring, are a cycloaliphatic radical or a keto group!, j, l and n are zero, 1 or 2, and k and m are zero or 1, with the proviso that n = zero if k = zero, m = zero if n = zero, and 1 ? j + 1 + n ? 3, -A1, -A2 and -A3 are an aromatic, heterocyclic or aliphatic ring system, -M1 and -M2 are -CO-O, -O-CO, -CH2CH2, -CH=CH, -CH2O, -OCH2 or -C=C, and X is CH=CH or CH2-CH2. The particular advantage of the compounds of the general formula (I) is that they are able to induce a high twisting power in a cholesteric phase, but without significantly affecting, in the smectic C* phase, the magnitude of the spontaneous polarization already present in a mixture. They are therefore suitable for pitch compensation, in particular for ferroelectric liquidcrystal mixtures.
