Study of Ethylene Polymerization Kinetics by TiCl4/Mg(OC2H5)2 Catalyst and Determination of the Active Sites Concentration [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2008
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.
