Подозреваю, что речь идет об этом, но времени, чтобы разобраться катастрофически не хватает.

A bimodal linear medium density polyethylene composition made by copolymerizing ethylene (monomer) and at least one (C3-C20)alpha-olefin (comonomer) with a mixture of a bimodal catalyst system and a trim solution in the presence of molecular hydrogen gas (H2) and an inert condensing agent (ICA) in one, two or more polymerization reactors (e.g., one fluidized bed gas phase reactor) under (co)polymerizing conditions; wherein prior to being mixed together the trim solution consists essentially of a (tetramethylcyclopentadienyl)(n-propylcyclopentadienyl)zirconium complex and an inert liquid solvent (e.g., liquid alkane) and the bimodal catalyst system consists essentially of an activator species (e.g., a methylaluminoxane species), a bis(2-pentamethylphenylamido)ethyl)amine zirconium complex and a (tetramethylcyclopentadienyl)(n-propylcyclopentadienyl)zirconium complex, all disposed on a solid support (e.g., a hydrophobic fumed silica); and wherein the (co)polymerizing conditions comprise a reaction temperature from 80 degrees (°) to 110° Celsius (C.), a molar ratio of the molecular hydrogen gas to the ethylene (H2/C2 molar ratio) from 0.001 to 0.050; and a molar ratio of the comonomer to the ethylene (Comonomer/C2 molar ratio) from 0.005 to 0.10.
