Gas phase polymerization process

TL;DR: In this paper, a vehicle axle construction comprises a suspension for supporting the axle from first and second frame rail members, and a double acting rack-and-pinion steering mechanism may be rigidly coupled to the axle for use in steering the wheels of the vehicle.

TL;DR: In this article, the additive may be selected from a group consisting of an aluminum distearate, an ethoxylated amine, polyethylenimines, and other additives suitable for use in the production of polymers for food contact applications and end products.

TL;DR: In this article, various processes, including continuous fluidized-bed gas-phase polymerization processes for making a high strength, high density polyethylene copolymer, comprising of contacting monomers that include ethylene and optionally at least one non-ethylene monomer with fluidized catalyst particles in a gas phase in the presence of hydrogen gas at an ethylene partial pressure of 100 psi or more.

TL;DR: In this article, a system and method for olefin polymerization is described, which includes polymerizing one or more olefins within a reactor having at least one of the injection tubes having two or more concentric flow paths.

TL;DR: In this article, substantially linear olefin polymers are disclosed which have very good processability, including processing indices (PI's) less than or equal to 70 percent of those of a comparative linear OLEF polymer and a critical shear rate at onset of surface melt fracture of at least 50 percent greater than the critical hear rate of a traditional linear OE polymer at about the same I2 and Mw /Mn.

TL;DR: In this paper, the authors proposed a method for copolymerizing alpha-olefins either alone or in combination with one or more other ALOIs in a gas phase reactor having a fluidized bed and a fluidizing medium such that the fluidization medium entering the reactor comprises a gas and a liquid phase.

TL;DR: In this paper, a continuous gas fluidized bed process is described for the production of polymer from monomer, in which a gaseous stream comprising monomer is passed through a fluid-ized bed in a reaction zone in the presence of catalyst under reactive conditions.

TL;DR: In this paper, a process for increasing the space time yield of polymer production in a fluidized bed reactor employing an exothermic polymerization reaction by cooling the recycle stream to below its dew point was described.
