Polymerization catalyst |
| abstract |
An olefin polymerization catalyst produced by copulverizing a magnesium compound and a scandium halide, such as magnesium chloride and scandium chloride which is thereafter treated with one or more Group 4b or 5b transition metal compounds, which when used as a cocatalyst with an organoaluminum compound produces polymers in higher yields than magnesium compounds copulverized with organic esters as previously practiced and having broad molecular weight distribution. |
