ABSTRACT:
A process for preparing alpha olefin waxes comprising polymerizing an ethylene containing gas in the presence of a hydrocarbon-soluble catalyst comprising a zirconium compound, a dialkyl aluminum halide and a monoalkyl aluminum dihalide in specified ratios in the presence of a diluent at 75.degree.-200.degree. C. and maintaining the mole ratio of ethylene to total olefin reaction product above 0.8 so as to produce a waxy product containing at least 90 mole % linear olefins of which greater than 50 wt % are C.sub.20+ waxes.
