Abstract

An olefin polymerization process comprising contacting one or more olefins and a catalyst component in a reaction zone under suitable reaction conditions to form a polyolefin, wherein the catalyst component is characterized by the formula: B(Cp)(Fl)MQ 2 wherein M comprises a metal, Q comprises a halogen, an alkyl group or an aryl group or combinations thereof, Cp comprises a cyclopentadienyl group, Fl comprises a fluorenyl group, B is a bridging group that may be characterized by the general formula —YRH wherein Y comprises C or Si and R comprises an alkyl group, an aryl group, a poly-aryl group or combinations thereof.

Claims

exact text as granted — not AI-modified
1 - 11 . (canceled) 
     
     
         12 . A polyolefin produced by the process of claim  8  wherein the catalyst component is characterized by formula A and wherein the polyolefin comprises highly isotactic polypropylene having a molecular weight of from 100,000 to 1,000,000 Daltons, a melting temperature of from 159° C. to 161° C. and a tacticity of from 97% to 99% mmmm. 
     
     
         13 . A polyolefin produced by the process of claim  8  wherein the catalyst component is characterized by formula B, D or F and wherein the polyolefin comprises syndiotactic polypropylene having a molecular weight of from 100,000 to 800,000 Daltons and a melting temperature of from 135° C. to 160° C. 
     
     
         14 . A polyolefin produced by the process of claim  8  wherein the catalyst component is characterized by formula C and wherein the polyolefin comprises isotactic polypropylene having a molecular weight of from 100,000 to 1,000,000 Daltons and a melting temperature of from 120° C. to 145° C. 
     
     
         15 . A polyolefin produced by the process of claim  8  wherein the catalyst component is characterized by formula E and wherein the polyolefin comprises isotactic polypropylene having a molecular weight of from 100,000 to 800,000 Daltons and a melting temperature of from 120° C. to 145° C. 
     
     
         16 . A polyolefin produced by the process of claim  8  wherein the polyolefin is a random propylene-ethylene copolymer produced with catalyst component A and has a melt flow rate of 10 g/10 min to 1000 g/10 min. 
     
     
         17 . A polyolefin produced by the process of claim  8  wherein the polyolefin is a random propylene-ethylene copolymer produced with catalyst component C and E and has a melt flow rate of 0.1 g/10 min to 500 g/10 min. 
     
     
         18 . A polyolefin produced by the process of claim  8  wherein the polyolefin is a propylene-ethylene rubber produced with catalyst component C and E, and has an ethylene content from 1 wt. % to 50 wt. % and a melt flow rate of 0.1 g/10 min to 500 g/10 min. 
     
     
         19 . A polyolefin produced by the process of claim  8  having a tacticity of from 97% mmmm to 99% mmmm. 
     
     
         20 . (canceled)
