Abstract (en)
[origin: WO2008061826A1] A method for the production of a polyethylene wax by the polymerization of ethylene in the presence of a Ziegler-Natta catalyst system which is composed of titanium tetrachloride and dialkylaluminum halide, wherein (the polymerization temperature lies in the range of 170 °C to 200 °C, the polymerization is carried out essentially in the absence of solvents, and the Al/Ti mole ratio is smaller than 1.6) a wax results with the following characteristics profile: - Ubbelohde melting point from 115 °C to 125 °C, - penetration value of maximum 1 mm · 10<SUP>-1</SUP>; - viscosity at 150 °C of less than 60 mPas; - density from 0.945 to 0.960 g/cm<SUP>3</SUP> at 23 °C; molar mass of less than 1500 g/mol, and - crystallinity of more than 70%.
