Abstract: Polyethylene is made by (co)polymerizing ethylene in a gas-phase reactor using a catalyst system comprising a chromium catalyst and a Group 4 transition metal catalyst, co-supported on an inorganic oxide support. The Group 4 transition metal catalyst is defined by the formula shown, wherein M is a Group 4 metal, P1 is a phosphinimide or ketimide ligand (shown), L is a monoanionic ligand which is a cyclopentadienyl or a bulky heteroatom type ligand, m is 1 or 2, n is 0 or 1, and p is an integer. The co-supported catalyst system gives access to polyethylene having a broad or bimodal molecular weight distribution. In the copolymerization of ethylene, reversed or partially reversed comonomer distribution is achieved: the Group 4 component provides polymer segments having higher molecular weight and also higher comonomer incorporation than polymer segments produced at the chromium sites. (Formulae I,II,III).

Abstract: Catalyst systems for polymerizing olefins include a catalyst comprising chromium and a cocatalyst comprising a substituted or unsubstituted non-transition metal cyclopentadienyl (Cp) compound. The catalyst also comprises an inorganic oxide support. Methods of preparing a catalyst comprise contacting a support with chromium and with a non-transition metal Cp compound. The support can be contacted with a solution comprising the non-transition metal Cp compound prior to entry into a reaction zone. Methods of polymerizing at least one olefin include contacting the olefin with a catalyst comprising chromium and with a cocatalyst comprising a non-transition metal Cp. The polymerization can be performed in the presence of hydrogen. Using the cocatalyst in conjunction with the catalyst increases several properties of the polymers produced by this method. Polymer compositions produced by such methods have various unique properties, including a PDI greater than 30.

Abstract: Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomoer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5 DEG C to 170 DEG C can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.
