ZIEGLER-NATTA CATALYST COMPOSITION WITH CONTROLLED MORPHOLOGY

摘要

Catalyst Systems, processes of forming the same and polymers and polymerization processes are described herein. The process of forming the catalyst system generally includes providing a first compound including a magnesium dialkoxide and aluminum alkoxide; contacting the first compound with a first agent and a second agent to form a solution of reaction product "A", the first agent including a titanating agent and the second agent including a first metal halide; contacting the solution of reaction product "A" with a third agent to form a solid reaction product "B", the third agent including a second metal halide; contacting the solid reaction product "B" with a fourth agent to form a solid reaction product "C", the fourth agent including a third metal halide; optionally contacting the solid reaction product "C" with a fifth agent to form a solid reaction product "D", the fifth agent including a fourth metal halide; and contacting the solid reaction product "C" or "D" with a sixth agent to form a catalyst component, the sixth agent including a first organoaluminum compound.
