Abstract:
The present invention relates to low density polyethylene having a melt flow rate (MFR) according to ISO 1133 (190° C., 2.16 kg) which is higher than 4.0 g/10 min, a storage modulus G′, measured at a loss modulus G″ 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.
