    Abstract: The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system that is comprised of (I) a compound which contains at least one labile halogen atom and (II) a Group III-B metal containing catalyst component which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component, and (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component.

    Abstract: Provided is a method of polymerizing olefins and a catalyst system for polymerizing olefins. In one embodiment, the method of polymerizing olefins comprises combining under polymerization conditions an olefin monomer; an activator; and a bridged metallocene compound comprising two Cp groups and a trivalent bridging group (A); the group (A) comprising at least one A moiety and at least three linkages between the A moiety and the two Cp ligands; wherein the Cp groups are independently selected from the group consisting of cyclopentadienyl, tetrahydroindenyl, indenyl, heterocyclic analogues thereof and substituted analogues thereof. An example of the bridged metallocene compound is represented in the structure: 1 wherein the Cp rings may be substituted as described herein; and the A moiety is silicon in this example. The catalyst system also includes one or more activators, and may also include a support material, wherein the activator and/or the metallocene may be supported on the support material.

    Abstract: A supported catalyst for olefin polymerization comprises a combination of a novel metal oxide support and an activator which is an aluminoxane or a boron activator. The novel metal oxide support of this invention is a conventional particulate metal oxide support material (such as silica or alumina) which has been treated with a halosulfonic acid. A catalyst system which contains this novel catalyst support and a transition metal catalyst is highly active for olefin polymerization (in comparison to prior art catalyst systems which use a conventional metal oxide support).

    Abstract: A method of making a solid procatalyst composition for use in a Ziegler-Natta olefin polymerization catalyst composition, said method comprising: contacting a precursor composition comprising a magnesium compound with a titanium halide compound and an internal electron donor in any order, in a suitable reaction medium to prepare a solid procatalyst composition, separating the solid procatalyst from the reaction medium, extracting the solid procatalyst composition by contacting the same one or more times with a liquid diluent at an elevated temperature for a period of time sufficient to prepare a solid procatalyst composition having a decreased titanium content compared to the titanium content of the solid procatalyst composition before said extraction, and recovering the solid procatalyst composition.
