Study of Ethylene Polymerization Kinetics by TiCl4/Mg(OC2H5)2 Catalyst and Determination of the Active Sites Concentration [PDF]
Ethylene was polymerized in slurry phase over a TiCl4/Mg(OC2H5)2 catalyst activated by Al(C2H5)3. It was shown experimentally that mass transfer resistance has no effect on polymerization kinetics.

Gas phase polymerization of ethylene towards UHMWPE [PDF]
For the first time, ultra-high molecular weight polyethylene (UHMWPE) was produced in gas phase process with a new fluidized bed concept where the solids are dispersed phase and the gas is bulk phase as opposed to conventional fluidized bed reactors (FBRs).
