摘要： Copolymer are formed by polymerizing C4 to C7 isoolefin monomers and alkyl-styrene monomers. The method comprises first providing feed streams into a reactor. The various feed streams provide monomers, a polar diluent or polar diluent mixture, and a catalyst system into the reactor. In the reactor, the feed streams contact one another so that the monomers form a polymer in a stable slurry, wherein the amount of polymer in the slurry yields a slurry concentration greater than 22 wt %. The ratio of moles of polymer formed per mole initiator is in the range of 0.25 to 4.0 moles polymer per mole of initiator.

摘要： The disclosure provides for a process and polymerization system to produce isoolefin polymers (72) utilizing polymorphogenates (16, 26) in the catalyst system to control polydispersity (MWD). The disclosure also provides a catalyst system (20) comprising a plurality of active catalyst complex species (34) formed by combination of a Lewis acid (24), an initiator (22) and a polymorphogenate (26), as well as polymers made using the catalyst system or process. The polymorphogenate (16, 26) can promote or mimic the formation of different active catalyst complex species (34) having different polymerization rates, i.e. different rates of propagation, chain transfer, or termination, as observed by different polydispersities resulting from the presence of relatively different proportions of the polymorphogenate.

摘要： The present invention relates to an in-line method for generating comonomer, such as 1-hexene or 1-octene, from monomer, such as ethylene. The comonomer generated is directly transported, without isolation or storage, to a polyethylene polymerization reactor. The in-line method for generating comonomer includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to a polyethylene polymerization reactor; feeding ethylene monomer and a catalyst in a solvent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer, and comonomer; and passing the gas stream to the polyethylene polymerization reactor to provide the necessary comonomer input. The in-line method is useful in the production of LLDPE, and other branched polyethylene based polymers. Some benefits include process simplification and reduced capital and operating costs.
