  • Publication number: 20070094920
    Abstract: The use is described of polymers which contain, in copolymerized form, an ?-olefin, a vinyl ester and an ester of an ?,?-unsaturated carboxylic acid as an additive for fuel oils and lubricants and in particular as a cold flow improver in fuel oils. In addition, the fuel oils and lubricants additized with these polymers; and also additive packages comprising such polymers are described.

  • Publication number: 20070063189
    Abstract: The invention relates to fluoranthene derivatives of the general formula (I) in which R1, R2, R3 and a are each defined according to the description, with the proviso that at least one of the R1 or R2 radicals is not hydrogen, to processes for their preparation and to the use of the fluoranthene derivatives as emitter molecules in organic light-emitting diodes (OLEDs), to a light-emitting layer comprising the inventive fluoranthene derivatives as emitter molecules, to an OLED comprising the inventive light-emitting layer and to devices comprising the inventive OLED.

  • Publication number: 20070041926
    Abstract: A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
