Abstract

PURPOSE: To obtain a low-melt flow index polymer in high yields, by (co)polymerizing ethylene at high pressure and temperature by use of a highly active Ziegler catalyst obtained from an organic Al compound, a titanium compound, etc.
CONSTITUTION: A catalyst is prepared by combining (A) a mixture containing at a specific mole ratio organic Al compounds represented by formulas I and II, wherein R1, R2 and R3 are each a C1WC10 hydrocarbon, X1 is a halogen or H, 0≤m≤2 and 1≤n≤2, or a mixture containing at a specified mole ratio an organic Al compound of formula I and an alkylsiloxalane derivative represented by formula III, wherein R4WR8 are each a C1WC10 saturated hydrocarbon or H, with (B) a solid product obtained by contacting a titanium compound with an activated magnesium dihalide. 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.
