Abstract: A conductive polyoxymethylene composition comprising a first polyoxymethylene component, a conductive filler, at least one boron oxyacid or salt thereof, and at least one first polyamide oligomer is disclosed. The first polyoxymethylene component comprises a copolymer of oxymethylene, a homopolymer of oxymethylene, and mixtures thereof, and is present in an amount of from about 50 to about 99.5 weight percent based on the total weight of the composition. The conductive filler is present in an amount of from about 0.1 to about 40 percent by weight based on the total weight of the composition. The boron oxyacid or salt thereof and the first polyamide oligomer stabilize the composition such that articles formed therefrom exhibit reduced or eliminated deterioration. Further, when exposed to higher temperature, pressure, and high-fuel content environments, the articles maintain the desired physical properties.

Abstract: The preparation of alkylaryl compounds takes place by a) reaction of a C4/C5-olefin mixture over a metathesis catalyst to prepare a C4-8-olefin mixture comprising 2-pentene, and optional removal of the C4-8-olefin mixture, b) removal of from 5 to 100% of the 2-pentene present in stage a) and subsequent reaction over an isomerization catalyst to give a mixture of 2-pentene and 1-pentene which is returned to stage a), c) dimerization of the C4-8-olefin mixture obtained in stage b) following removal in the presence of a dimerization catalyst to give a mixture containing C8-16-olefins, removal of these C8-16-olefins and optional removal of a partial stream thereof, d) reaction of the c8-16-olefin mixtures obtained in stage c) or of the partial stream with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds where, prior to the reaction, 0 to 60% by weight, based on the c8-16-olefin mixtures obtained in stage c), of linear olefins may additionally be added, e) opt

Abstract: In a process for rectificatively separating liquids comprising (meth)acrylic monomers in a rectification column, a stream is withdrawn from the rectification column and recycled into the rectification column as a molecular oxygen-enriched liquid phase.

Abstract: Pigment concentrates comprising at least one pigment and one polyolefin wax prepared from one or more olefins by catalysis with a single-site catalyst comprising a transition metal of groups 5 to 8 of the Periodic Table, where the complex contains not more than one cyclopentadienyl system per transition metal atom, the concentrates comprising a thermoplastic, if desired, and additives, if desired.

Abstract: A process for preparing polyetherols by ring-opening polymerization of alkylene oxides onto H-functional initiator molecules, which comprises at least one process step a) in which a compound of the formula (I)
