Abstract

Solid polyethylene is made by heating ethylene with titanium hydride and titanium tetrachloride in a weight ratio between 0,3 : 1 and 3 : 1 at a temperature of 150 DEG -250 DEG C. under an ethylene partial pressure of at least 50 p.s.i., in an inert liquid reaction medium which is a solvent for ethylene. The term "titanium hydride" means a composition of the formula TiHx where x is greater than zero but not greater than 2. The liquid medium may be pentane, hexane, heptane, cyclohexane, octane, benzene, xylene, or toluene. The polyethylene is purified by boiling with an isopropanol-HCl solution.
