| titleOfInvention | Polyolefin production |
| abstract | Use of a metallocene catalyst component for the preparation of a syndiotactic polyolefin having a monomer length of up to C10, which component has the general formula: R"(CpR1R2) (Cp'R1'R2') MQ2 wherein Cp is a cyclopentadienyl ring; Cp' is a 3,6 di substituted fluorenyl ring; R1 and R2 are each independently H or a substituent on the cyclopentadienyl ring which is proximal to the bridge, which proximal substituent is linear hydrocarbyl of from 1 to 20 carbon atoms or a group of the formula XR*3 containing up to 7 carbon atoms in which X is chosen from Group IVA, and each R* is the same or different and chosen from hydrogen or alkyl; R1' and R2' are each independently substituent groups on the fluorenyl ring, each of which is a group of the formula AR'''3, in which A is chosen from Group IVA, and each R''' is independently hydrogen or a hydrocarbyl having 1 to 20 carbon atoms; M is a Group IVB transition metal or vanadium; each Q is hydrocarbyl having 1 to 20 carbon atoms or is a halogen; R" is a structural bridge imparting stereorigidity to the component and comprises the moiety TRaRb, in which T is chosen from group IVA, and each of Ra and Rb is independently (i) substituted or unsubstituted aryl linked to T directly or by C1-C4 alkylene; or (ii) H. |
