Abstract: The invention relates to a method for producing ethylene/vinyl acetate copolymers in which a mixture comprised of ethylene and vinyl acetate is continuously polymerized in the presence of radical polymerization initiators and optional molecular weight modifiers in a cooled tubular reactor at a pressure ranging from 1000 to 3500 bar. The polymerization initiator is charged at the beginning and at a number of positions along the tubular reactor, and the temperature changes i n the reaction mixture range no more than 20.degree.C between the first maximum temperature and the last charging of the polymerization initiator along the tubular reactor.

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 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.
