COPOLYMERIZATION OF ETHYLENE AND 1-HEXADECENE WITH CP2ZRCL2-METHYLALUMINOXANE CATALYST

The metallocene catalyst system Cp2ZrCl2-methylaluminoxane showed surp risingly high activity for 1-hexadecene, and high concentrations of co monomer could be incorporated into the copolymer compared with a heter ogeneous titanium catalyst. A temperature rising elution fractionation (TREF) fractogram of the copolymer revealed it to have narrow branchi ng distribution, much narrower than in commercial linear low density p olyethylene, and to have features in common with a commercial low dens ity polyethylene.
