Abstract
Process for the preparation of ethylene polymers The preparation of polyethylene and ethylene-1-olefin copolymers in the suspension or gas phase process with the aid of metallocene/aluminoxane catalysts whose metallocene component is a bridged biscyclopentadienyl complex offers particular advantages.
Depending on the structure of the complex, the use of these complexes gives, with high activity, products in a very broad molecular-weight range and permits the production of very varied grain morphologies of the products, such as high and low bulk density, extremely small and extremely large mean grain diameters and various grain shapes. The variety of grain morphologies which can be achieved opens up various possibilities for the use of such polyethylene powders in sintering processes.
