Propylene was polymerized with metallocene and Ziegler-Natta mixedcatalytic systems to obtain reactor blends of metallocene and Ziegler-Natta-derived propylene homopolymers. The two catalytic systems are able to act jointly, providing individual polymers with different melting and crystallization te

## Abstract Catalytic activity during the formation of polyethylene (PE)/clay nanocomposites by __in situ__ polymerization with metallocenes was studied. Ethylene polymerization was carried out with the homogeneous metallocene in the presence of the clay particles and using the clay‐supported metal
## Abstract In the polymerization of olefins with Group 4 metallocene dichlorides or dimethyl derivatives as procatalysts the use of polymethylaluminoxane (MAO) as the cocatalyst, especially in extreme excess (10^2^–10^3^ times the metallocene equivalent), has been shown to have an extraordinary ac
