ABSTRACT:
A process for producing an ethylene-.alpha.-olefin copolymer which comprises copolymerizing ethylene and an .alpha.-olefin at a temperature higher than 120.degree. C. by using a catalyst system comprising a specified titanium amide compound represented by general formula (R.sup.1 R.sup.2 N).sub.4-n TiY.sub.n and an oxygen-containing alkylaluminum compound. According to the above process, there can be obtained ethylene-.alpha.-olefin copolymers narrow in composition distribution, high in molecular weight and excellent in weather resistance, colorizability, corrosion resistance and dynamic properties.
