摘要：
The metallocene catalyst system Cp2ZrCl2-methylaluminoxane showed surprisingly high activity for 1-hexadecene, and high concentrations of comonomer could be incorporated into the copolymer compared with a heterogeneous titanium catalyst. A temperature rising elution fractionation (TREF) fractogram of the copolymer revealed it to have narrow branching distribution, much narrower than in commercial linear low density polyethylene, and to have features in common with a commercial low density polyethylene.
