Abstract: The present invention provides a polymer composition comprising a polymer and an antioxidant comprising a diarylamine-based compound represented by General Formula (1): where, in General Formula (1), A1 and A2 each independently represent a C6 to C18 arylene group which may have a substituent, and A3 and A4 each independently represent an organic group having a cyclic imide structure which may have a substituent.
Abstract: We provide a method for operating a navigation system for a motor vehicle in a road network, and to a navigation system. To this end, first a zone of the road network is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle is associated with at least one emissions class. First, information about the geographical location of the zone and about the emissions class at least required there is stored in the navigation system. Then, information about the at least one emissions class of the motor vehicle is entered into the navigation system. Thereafter, the information entered is considered in the destination guidance process, wherein destination guidance into or through the zone is avoided if the at least one emissions class of the motor vehicle is affected by emissions class-dependent drive-through restrictions in the zone.

Abstract: Coal-water slurries containing a rheological additive are provided. Rheological additives employed for preparation of the coal-water slurries are ester-amide products obtained by reaction of a polycarboxylic acid with a polyether glycol and aliphatic amine. Salts of the ester-amides may also be advantageously employed as dispersants. The ester-amide additives are employed in an amount from about 0.1 to about 4 percent by weight of the slurry. Stable aqueous slurries containing from 60 to 80 percent by weight coal solids are produced.
Abstract: A diesel fuel and injector cleaning additive which comprises a solvent such as a (C.sub.3 -C.sub.5) alcohol and an amino alkylene-substituted asparagine.
