  • Olefin polymerization process in the presence of a radical generating system
    Patent number: 7378476
    Abstract: An olefin polymerization process comprises gas-phase polymerization of at least one olefin monomer in a reactor using a Ziegler-Natta or metallocene catalyst system in the presence of at least one suitable radical-generating compound in an amount sufficient for polymer modification and subsequent stabilization of such compound and generated radicals before post-reactor heat processing.

  • Agitator for a horizontal polymerization reactor having contiguous paddle stations with paddles and sub-stations with sub-station paddles
    Patent number: 6350054
    Abstract: Improved apparatus for mechanically stirring a quench-cooled subfluidized particulate bed of polymerized monomer lowers lumping of polymer particles by using substantially contiguous paddle stations disposed along the drive shaft within the reactor in combination with a plurality of sub-stations in at least one paddle station class, each sub-station having a width along the shaft of no more than 50 percent of the total width of the paddle station, and sub-station paddles attached to the shaft at each sub-station so as to sweep through the particulate bed.
