Abstract
Polyethylene is made by polymerizing ethylene in the presence of a catalyst comprising ethyl aluminium sesquichloride and TiCl4 in a molar ratio of between 8:1 and 20:1, by introducing the catalyst components directly into the polymerization reactor, reacting them, before polymerization, in an inert atmosphere, and for a time sufficient to ensure reduction of the TiCl4. A small amount of an ether may also be present with the catalyst components. The polymerization is effected in a hydrocarbon medium. The reaction is terminated by the addition of methanol. The polyethylene has a melting point in the range of 200-250 DEG C., and a reduced viscosity between 9 and 24.
