Abstract
PURPOSE: To obtain a low-melt flow index polymer in high yields, by (co)polymerizing ethylene at high temperature and pressure by use of a highly active Ziegler type catalyst prepared from an organometallic compound, a titanium compound, etc.
CONSTITUTION: A catalyst, is prepared by combining (A) an organometallic compound, e.g., trimethylaluminum, or an alkylsiloxalane derivative, e.g., trimethyldisiloxalane, with (B) a solid product, Ti content 0.1W10wt%, obtained by contacting an alkoxy group-containing titanium compound represented by the formula, wherein R' is a C1WC20 hydrocarbon, X' is a halogen and 0≤n≤4, with an activated magnesium dihalide, e.g., MgCl2, surface area ≥5m2/g. Then, the polymer of the purpose is obtained by (co)polymerizing ethylene at a high pressure of at least 200kg/cm2 and a high temperature of at least 125°C by use of the catalyst.
