Homogeneous metallocene catalysts for the polyolefin production show compared with conventional Ziegler systems remarkable advantages, like the possibilities to regulate the microstructure leading to optimized polymer properties. However, for industrial application it is necessary to immobilize the metallocenes on a heterogeneous support. The parameters which now influence polymerization kinetics, polymer growth, polymer morphology, the decisive particle fragmentation are demonstrated and summarized in a physical and mathematical model.
