Abstract
PURPOSE: To prepare the titled polymer in high efficiency, at a low cost, by polymerizing ethylene under high temperature and pressure using a highly active catalyst composed of an organic metal compound and the product obtained by contacting an oxygen-containing Mg compound, a hologen-containing compound of a specific element, and a transition metal compound.
CONSTITUTION: The polymerization of ethylene, etc. is carried out under a pressure of >200kg/cm2 at ≥125°C using a catalyst composed of (A) an organic metal compound (e.g. diethyl aluminum chloride) or an alkylsiloxalane derivative (e.g. trimethyl-diethylsiloxalane) and (B) a solid composition which is a product obtained by contacting (i) an oxygen-containing magnesium compound (e.g. magnesium oxide), (ii) a halogen-containing compound of an element of the IIIbW VIb group of the periodic table (e.g. aluminum chloride) and (iii) a compound of a transition metal of the IVa or Va group of the periodic table (e.g. titanium tetrachloride).
