    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: A process is described for copolymerizing ethylene with vinyl esters and, if desired, with further vinylic comonomers in a tube reactor at pressures of from 500 to 4000 bar and at not more than 220° C., which comprises initiating the free-radical polymerization at at least two locations of the tube reactor by adding a catalyst/initiator and adjusting the temperature profile within the reactor such that the temperature maxima downstream of the initiation locations are from 150 to 220° C. and differ by less than ±10° C. from one another.

    Abstract: A process is disclosed for preparing ethylene polymers with a molecular weight Mw (weight average) lower than 20,000 g/mole at temperatures in a range from 200 to 280 DEG C and pressures in a range from 1000 to 3500 bars in the presence of a catalyst system. The catalyst system used contains: (A) a non-bridged substituted or unsubstituted biscyclopentadienyl complex; (B) a metal compound of general formula (I) M (R )r (R )s (R )t, in which M is an alkaline, an alkaline earth metal or a metal of the third main group of the periodic table; R is hydrogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl or arylalkyl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R and R independently represent hydrogen, halogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl, arylalkyl or alkoxy with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; r is an integer from 1 to 3; and s and t are integers from 0 to 2, the sum r+s+t corresponding to the valency of M ; and (C) a metallocene ion-forming compound selected in a group which consists of strong, neutral Lewis acids, ionic compounds with lewis acid cations and ionic compounds with Brönsted acids as cations. Components (A), (B) and (C) are mixed together and after at the latest 5 minutes are dosed in the reactor.
