POLYETHYLENE BIMODAL |
| abstract |
The invention described herein relates to a method for preparing a catalytic compound suitable for the preparation of bimodal polymers which comprises the steps of: a) preparing hollow polyethylene beads of controlled size and shape; b) drying the hollow beads under vacuum; c) impregnation of the dry hollow balls with a concentrated solution of the desired catalyst under reduced pressure; d) slow return to atmospheric pressure of the impregnated hollow balls; e) drainage of the excess liquid; f) drying under inert gas at atmospheric pressure. It also relates to a method for preparing bimodal polymers which uses these novel catalytic compounds. |
