Abstract:
A catalyst system including two or more metallocene catalysts and processes for using the same to produce polyolefin polymer compositions are provided. The polyolefin polymer compositions have a good balance of a melt index ratio and normalized melt strength.

Claim (Index 1):
A catalyst system comprising the product of the combination of:\n a) two or more metallocene catalysts each independently represented by the formula\n L A L B L C i MAD, \n wherein L A  and L B  are each independently substituted cyclopentadienyl or heterocyclopentadienyl groups \u03c0-bonded to M, containing from one to five substituent groups R, each R independently being a radical independently selected from hydrocarbyl, hydrocarbyl silyl or hydrocarbylgermyl groups having from 1 to 20 carbon atoms, silicon or germanium atoms, substituted hydrocarbyl, hydrocarbyl silyl or hydrocarbylgermyl radicals wherein one or more hydrogen atoms is replaced by a halogen radical, an amido radical, a phosphido radical, an alkoxy radical, an aryloxy radical, either of L A  or L B  may be a cyclopentadienyl ring in which at least two adjacent R groups are joined together and along with the carbon atoms to which they are attached to form a ring system having from 4 to 20 carbon atoms which may be saturated, partially unsaturated or aromatic, and substituted or unsubstituted and, the L A  and L B  ligands are covalently bridged together through a Group 14 linking group; L C i  is an optional neutral, non-oxidizing ligand having a dative bond to M, i equals 0 to 3; M is a Group 3-6 transition metal; and A and D are independently monoanionic labile ligands, optionally bridged to each other or L A  or L B , each having a \u03c3-bond to M; wherein the catalyst system comprises a first metallocene catalyst having at least one of L A  or L B  with at least one C 3  or greater hydrocarbyl, hydrocarbyl silyl or hydrocarbylgermyl substituent and a second metallocene catalyst having at least one of L A  or L B  with only one or more methyl hydrocarbyl substituents; b) at least one activator; and c) optionally, at least one support.
