場合、沸騰へキサンに抽出される低密度成分(ヘキサン

のベタツキが悪化するという傾向がある。In these methods, trialkylaluminum having an alkyl group having 2 or more carbon atoms, such as triethylaluminum and triisobutylaluminum, is specifically used as the organoaluminum component. However, in such a catalyst system, an ethylene copolymer with a density of o and 5zsf/- or less can be produced by copolymerizing ethylene with an α-olefin having 3 or more carbon atoms, especially an α-olefin having 5 or more carbon atoms. In this case, the molecular distribution widens as the density decreases. Generally, when the molecular weight distribution widens as the density decreases, the amount of low-density components extracted by boiling hexane (hexane extract) also increases significantly, which tends to deteriorate film strength and film surface stickiness.

In particular, when producing an ethylene copolymer with a density of 0.925 f/- or less by copolymerization with an α-olefin having 5 or more carbon atoms, if copolymerization with a narrow molecular weight distribution is possible, it would be possible to Compared to polymers, it is expected that the strength of the film will be improved, the stickiness of the film will be eliminated, and the amount of slip agent added to prevent film stickiness can be reduced, so it has great industrial advantages.
