Abstract
PURPOSE: To obtain a low-density ethylene copolymer, by polymerizing ethylene using a catalyst comprising a titanium catalyst component with a specific specification supported by a magnesium compound and an aluminum compound, followed by copolymerization of ethylene and an α-olefin.
CONSTITUTION: In the preparation of an ethylene copolymer with a density of 0.900W0.945g/cm3 by copolymerizing ethylene with a small ratio of an α-olefin having 3 or more C at a temperature not higher than 100°C using a catalyst comprising A) a titanium catalyst component supported by a magnesium compound and B) an organoaluminum compound, A) the component consists of A-1) a substance having a specific surface area not less than 40m2/g, an average particle diameter of 5W200μ, and a standard deviation of particle size distribution not more than 2.1 and/or A-2) a substance having a specific surface area not less than 80m2/g and an organic acid ester in an amount 0.1W7mol times based on titanium. Before copolymerization 0.01W40g of ethylene per gram of titanium catalyst component is polymerized, and ethylene is copolymerized with α-olefin to give the ethylene copolymer.
