| titleOfInvention | Polymerization catalysts and bimodal polymer production process in a single reactor |
| abstract | A catalyst composition comprising a first metallocene compound, a second metallocene compound, an activator support, and an organoaluminum compound, wherein: (a) the first metallocene compound has the formula: (X1) (X2R1 2) (X3) (X4) M1; wherein (X1) is cyclopentadienyl, indenyl, or fluorenyl; (X2) is fluorenyl; (X1) and (X2) are connected by a disubstituted bridging group comprising an atom bonded to both (X1) and (X2), where the atom is carbon or silicon; a first substituent of the disubstituted bridging group is an aliphatic or aromatic group having from 1 to about 20 carbon atoms; a second substituent of the disubstituted bridging group is an unsaturated aliphatic group having 3 to about 10 carbon atoms; R1 is H, an alkyl group having 1 to about 12 carbon atoms, or an aryl group having 1 to about 12 carbon atoms; (X3) and (X4) are independently an aliphatic group, an aromatic group, a cyclic group, a combination of aliphatic and cyclic groups, or a substituted derivative thereof, having from 1 to about 20 atoms of carbon, or a halide; M1 is Zr or Hf; (b) the second metallocene has the formula: (X5) (X6) (X7) (X8) M2; wherein (X5) is a substituted or unsubstituted cyclopentadienyl, or substituted or unsubstituted indenyl, each substituent on (X5) is, independently, a linear or branched substituted or unsubstituted alkyl group, or a substituted or unsubstituted alkenyl group straight or branched unsubstituted, having 1 to about 20 carbon atoms; and (X6) is a substituted or unsubstituted cyclopentadienyl, or substituted or unsubstituted indenyl, each substituent on (X6) is independently a substituted linear alkyl group, a branched substituted or unsubstituted alkyl group, or an alkenyl group substituted or unsubstituted linear or branched, having from 1 to about 20 carbon atoms; (X7) and (X8) are independently an aliphatic group, an aromatic group, a cyclic group, a combination of aliphatic and cyclic groups, or a substituted derivative thereof, having from 1 to about 20 atoms of carbon, or a halide; and M2 is Zr or Hf. |
