    Abstract: Use of aqueous dispersions comprising at least one at least partially neutralized ethylene copolymer wax selected from among ethylene copolymer waxes which comprise, as comonomers in copolymerized form, (A) from 26.1 to 39% by weight of at least one ethylenically unsaturated carboxylic acid and (B) from 61 to 73.9% by weight of ethylene, and ethylene copolymer waxes which comprise, in copolymerized form, (A') from 20.5 to 38.9% by weight of at least one ethylenically unsaturated carboxylic acid, (B') from 60 to 79.4% by weight of ethylene and (C') from 0.1 to 15% by weight of at least one ethylenically unsaturated carboxylic ester, as auxiliaries for wastewater treatment.

    Abstract: Copolymers of ethylene have from 1 to 30 mol % of alkyl(meth)acrylates and, if desired, other comonomers, and have a residual comonomer content of less than 0.5% by weight in the copolymer. A process for preparing copolymers of this type in a combination of stirred autoclave and tubular reactor is described, as is the use of the copolymers for preparing polyamide molding compositions.

    Abstract: The present invention relates to a process for coating apparatuses and apparatus parts for chemical plant construction-which are taken to mean, for example, apparatus, tank and reactor walls, discharge devices, valves, pumps, filters, compressors, centrifuges, columns, dryers, comminution machines, internals, packing elements and mixing elements-wherein a metal layer or a metal/polymer dispersion layer is deposited in an electroless manner on the apparatus(es) or apparatus part(s) to be coated by bringing the parts into contact with a metal electrolyte solution which, in addition to the metal electrolyte, comprises a reducing agent and optionally the polymer or polymer mixture to be deposited in dispersed form, where at least one polymer is halogenated.

    Abstract: The temperature measurement probe consists of a probe member with a bore hole containing a thermocouple or a resistance thermometer, with its thermally sensitive tip extending out of the front. The front section of the probe member (1) has an annular gap (10) between it and the bore (2). The probe is preferably used for temperature measurements in high pressure polyethylene plants.

    Abstract: In a process for preparing ethylene-vinyl acetate copolymers in which a mixture of ethylene and vinyl acetate is polymerized continuously in the presence of free-radical polymerization initiators and, if desired, molecular weight regulators in a cooled tube reactor at a pressure in the range from 1000 to 3500 bar, and the poly-merization initiator is added at the beginning and at two or more points along the tube reactor, and temperature changes in the reaction mixture along the tube reactor, between the first temperature maximum and the last addition of the polymerization initiator, are within a range of not more than 20° C.
