Abstract: Separating system (1 to 11) for tubular reactors or autoclaves used for the polymerisation of ethylene or copolymerisation of ethylene with ethylenically unsaturated comonomers in the presence of initiators at pressures of from 500 to 4000 bar and temperatures of from 150 to 350 DEG C, for reducing the emission of solids during relaxation processes of the reaction mixture present in the reactor or autoclave, characterised in that the relaxed reaction mixture is passed through at least two separating tanks (1, 1a) installed in series, before reaching the atmosphere.

Abstract: A continuous process for the manufacture of ethylene copolymers under high pressure and at high temperature in a polymerization zone, with transfer of the reaction mixture into a high pressure product isolation zone and from there into a low pressure product isolation zone, and recycling of the unconverted gas from the high-pressure product isolation zone into the polymerization zone and from the low pressure product isolation zone into a low temperature separator, from where the comonomer separated off is recycled to the polymerization process, whilst the ethylene is discharged as off-gas. The gas taken off the low pressure product isolation zone is preferably compressed to from 10 to 20 bar and cooled to from -10 to -30.degree.C before it is fed into the low temperature separator. There is a substantial improvement in the efficiency of separating off the comonomer.

Abstract: A process for the manufacture of ethylene polymers by polymerizing ethylene under high pressures and at high temperatures in the presence of from 0.01 to 0.5 per cent by weight of an alkyl ester (alkyl being of 1 to 8 carbon atoms) of an alkenemonocarboxylic acid of 3 or 4 carbon atoms. n-Butyl acrylate is a particularly suitable polymerization activator. Although the start temperature of the ethylene polymerization is relatively low, there is no difference in mechanical and optical properties of a blown film manufactured from the resulting ethylene polymer and of a blown film of pure polyethylene.

Abstract: A process for the manufacture of copolymers of ethylene with n-butyl acrylate in a polymerization zone at pressures above 800 atmospheres and at from 150 to 350.degree.C, wherein the reaction mixture obtained is transferred, via a cooling zone which is at a pressure below 500 atmospheres and at from 150 to 250.degree.C, into the high pressure product isolation zone, the mean residence time of the reaction mixture in the two zones being from 2 to 10 minutes. A copolymer which gives good films is obtained.

Abstract: The pressure in a continuous high pressure polymerization system, in which ethylene, with or without comonomers, is polymerized under high pressures and temperatures and the unconverted amounts of gas are recycled through the high pressure recycle gas system into the polymerization system, is rapidly reduced to below the particular reaction pressure when predetermined limiting pressure and/or temperature values are exceeded or when other faults occur by opening one or more pressure-relief apparatuses mounted on the high pressure polymerization system and transferring the hot let-down reaction mixture from the polymerization system via one or more let-down lines through one or more separator systems into the atmosphere, by a process in which the high pressure polymerization system is divided into a plurality of isolated sections at the same time as the let-down process is triggered and only the section in which the let-down process is triggered is let down to the atmosphere. Preferably, the sections in which the let-down process is not triggered can be let down into the high pressure recycle gas system, if necessary through a product separator, in synchronization with triggering of the let-down to the atmosphere.
