The present invention relates to low density polyethylene having a melt flow rate (MFR) according to ISO 1133 (190&#xb0; C., 2.16 kg) which is higher than 4.0 g/10 min, a storage modulus G', measured at a loss modulus G&#x2033; of 5 kPa, which is above 3000 Pa and a vinylidene content which is at least 24/100 k C, compositions, a process for production of the low density polyethylene, a low density polyethylene which is obtainable by the process, a continuous ethylene polymerization method for introducing vinylidene in a low density polyethylene, a method for an extrusion coating process or an extrusion lamination process, an article, e.g. an extrusion article, an extrusion lamination article, film blowing article, film casting article, wire and cable extrusion article, injection moulding article, blow moulding article or pipe extrusion article, and uses of the low density polyethylene.

Ethylene polymers for extrusion coating

A power cable includes a conductor surrounded by one or more layers. At least one of the layers can include a polymer composition having an electric conductivity of 0.50&#xd7;10S/m or less when measured according to DC conductivity method using a tape sample. The polymer composition can include a polyolefin which is obtainable by a high pressure polymerization process. This process includes: compressing one or more monomers under pressure in a compressor, in which a compressor lubricant, such as mineral oil is used for lubrication; polymerizing a monomer optionally together with one or more comonomers in a polymerization zone; and separating the obtained polyolefin from the unreacted products and recovering the separated polyolefin in a recovery zone.

The invention relates to a method for producing a polymer using a chain transfer agents. In particular, the invention relates to a process for polymerizing a polymer in the presence of a mixture of at least two chain transfer agents, which mixture comprises

Process for producing a polymer and a polymer for wire and cable applications

The present invention relates to an ethylene homo- or copolymerization process, characterized in that an inhibitor is added to the reaction mixture or any of its components before the reaction mixture is fed to the reaction zone. The present invention further relates to the use of an inhibitor to reduce fouling in an ethylene homo- or copolymerization process.
