Certain metallocene compounds are provided that, when used as a component in a supported polymerization catalyst under industrially relevant polymerization conditions, afford high molar mass homo polymers or copolymers like polypropylene or propylene/ethylene copolymers without the need for any α-branched substituent in either of the two available 2-positions of the indenyl ligands. The substituent in the 2-position of one indenyl ligand can be any radical comprising hydrogen, methyl, or any other C-Chydrocarbon which is not branched in the α-position, and the substituent in the 2-position of the other indenyl ligand can be any C-Chydrocarbon radical with the proviso that this hydrocarbon radical is branched in the β-position. This metallocene topology affords high melting point, very high molar mass homo polypropylene and very high molar mass propylene-based copolymers. The activity/productivity levels of catalysts including the metallocenes of the present invention are exceptionally high.

A high impact strength random block copolymer including (a) about 65-97 wt. % of a crystalline propylene/ethylene copolymer A containing from about 0.5 wt. % to about 6 wt. % derived from ethylene and from about 94 wt. % to about 99.5 wt. % derived from propylene, and (b) about 3-35 wt. % of a propylene/ethylene copolymer B containing from about 8 wt. % to about 40 wt % derived from ethylene and from about 60 wt % to about 92 wt. % derived from propylene. The crystalline to amorphous ratio Lc/La of the random block copolymer ranges from about 1.00 to about 2.25. The random block copolymer is characterized by both high toughness and low haze.
