Polymerization process |
| abstract |
A process for preparing bimodal molecular weight distribution copolymers of ethylene with alpha-olefins having 3 to 20 carbon atoms, said copolymers having:(a) a comonomer distribution wherein the comonomer level at the mid-position of the low molecular weight component is <3 times the level at the mid-position of the high molecular weight component, and(b) a total average comonomer content in the range 0.5-20 short chain branches (SCB)/1000 C atoms characterised in that said process is carried out in the presence of a supported multisite catalyst. The multisite catalyst comprises a metallocene complex and a Ziegler catalyst. The metallocene complex for example is bis(pentamethylcyclopentadienyl) zirconium dichloride. |
