| titleOfInvention | Improved catalyst system for producing polyethylene copolymers in a high temperature solution polymerization process |
| abstract | (i) a metallocene complex of formula (I); (ii) an aluminoxane co-catalyst, and (iii) a catalyst system for preparing an ethylene copolymer in a hot solution process, optionally comprising a boron containing cocatalyst, is described: [Formula I] In the above formula (I), M is Hf or Zr, X is a sigma ligand, L is a bridge of the formula -SiR 8 2 -, wherein each R 8 is independently C 1 -C 20 -hydrocarbyl, tri(C 1 -C 20 -alkyl)silyl, C 6 -C 20 -aryl, C 7 -C 20 -arylalkyl or C 7 -C 20 -alkylaryl, n is 0, 1 or 2, R 1 and R 1′ may be the same or different and may be a linear or branched C 1 -C 6 -alkyl group, R 2 and R 2′ are the same or different and are a CH 2 -R 9 group, wherein R 9 is H or a linear or branched C 1 -C 6 -alkyl group, R 5 and R 5' are the same or different and can be H, or a linear or branched C 1 -C 6 -alkyl group or an OR group, where R is a C 1 -C 6 -alkyl group, R 6 and R 6′ are the same or different and can be H or a C(R 10 ) 3 group, wherein R 10 is the same or different and R 10 can be H, or a linear or branched C 1 -C 6 -alkyl group. or R 5 and R 6 and/or R 5′ and R 6′ together form an unsubstituted 4-7 membered ring fused to the benzene ring of the indenyl moiety, provided that when R 5 and R 6 as well as R 5′ and R 6′ together form an unsubstituted 5-membered ring fused to the benzene ring of the indenyl moiety, then R 2 and R 2′ are C 1 - not an alkyl group; R 7 and R 7′ may be the same or different and may be H, or a linear or branched C 1 -C 6 -alkyl group. |
