Bridged Metallocene Catalysts with a Pendant Group 13 Element, Catalyst Systems Containing Same, Processes for Making a Polymer Product Using Same, and Products Made from Same

Abstract

A catalyst system can include the metallocene compound, a non-coordinating anion type activator comprising a supported alumoxane or aluminum alkyl, and optionally a scavenger. A process for making a polymeric product can comprise: contacting a C2-C22 alpha-olefin feed with the catalyst system to obtain a polymerization reaction mixture; and obtaining a polymer product from the polymerization reaction mixture. A polymer product can be made by the process to exhibit at least an Mn from 7,000 g/mol to 70,000 g/mol and a PDI from 4.1 to 9.0.

What is claimed is: 
     
         1 . A polymer product made from an alpha-olefin feed comprising ethylene (C 2 ) monomer and a C 3  to C 40  alpha-olefin comonomer, wherein the polymer product exhibits, as measured by GPC:
 an Mn from 7,000 g/mol to 70,000 g/mol;   an Mw/Mn from 4.1 to 9.0; and   an average content of polymerized C 3  to C 40  alpha-olefin comonomer, relative to a total content of alpha-olefin monomers and comonomers polymerized in the polymer product, that increases for each quartile of increasing Mw/Mn of the polymer product.   
     
     
         2 . The polymer product of  claim 1 , further exhibiting, as measured by GPC, a span of content of copolymerized C 3  to C 40  alpha-olefins across the Mw/Mn of the polymer product that is no greater than 35% above or below a mean content of copolymerized C 3  to C 40  alpha-olefins across the Mw/Mn of the polymer product. 
     
     
         3 . The polymer product of  claim 1 , further exhibiting a melt index ratio, MIR, from 40 to 150.
