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.

Abstract: Preparation of ethylene polymers (A) by a high pressure process involves dissolving radical initiator(s) in ketone(s) (I); compressing; dosing the mixture to the polymerization reactor in one or more portions; and carrying out polymerization. Preparation of ethylene polymers (A) by a high pressure process involves: (1) dissolving radical initiator(s) in ketone(s) of formula R1-CO-R2 (I); (2) compressing; (3) dosing the mixture to the polymerization reactor in one or more portions; and (4) carrying out polymerization at 140-350 deg C and 400-4500 bars. R1, R2 = 1-6C alkyl or 3-12C cycloalkyl; or are linked to complete a 4-13 membered ring.

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.
