Manufacture of particulate polyethylene |
| abstract |
Manufacture of particulate polyethylene by polymerizing ethylene in an agitated bed of dry particulate polyethylene by means of a catalyst system comprising (1) a particulate inorganic carrier and (2) a Ziegler catalyst applied to said carrier. The catalyst system is used in the form of an intimate mixture of the catalyst system with a particulate ethylene polymer which does not soften at the polymerization temperature used, the particles in said mixture being coated with a saturated hydrocarbon wax which is solid at 30*C but liquid at the polymerization temperature used. This process makes it possible to obtain particulate polyethylene having a desirable particle size distribution. |
