Abstract:
The present invention relates to a low density polyethylene having a molecular weight distribution Mw/Mn which is 15 or less, a storage modulus G′, measured at a loss modulus G″ of 5 kPa, which is above 3000 Pa, a weight average molecular weight (Mw) which is between 192000 and 250000 g/mol and has a melt flow rate (MFR) according to ISO 1133 (190° C., 2.16 kg) which is higher than 3.0 g/10 min, 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 a method for 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 molding article, blow molding article or pipe extrusion article, and uses of the low density polyethylene.
