POLYOLEFIN POWDER, METHOD OF PRODUCTION AND USE THEREOF

The polyolefin powder contains particles with fluffy morphology. The method of preparation of polyolefin powder is carried out by the coordination polymerization of 1-olefins on the thermally-treated Ziegler-Natta precatalyst activated by the organoaluminium cocatalyst. La poudre de polyoléfine cont...

Beschreibung
Zusammenfassung:	The polyolefin powder contains particles with fluffy morphology. The method of preparation of polyolefin powder is carried out by the coordination polymerization of 1-olefins on the thermally-treated Ziegler-Natta precatalyst activated by the organoaluminium cocatalyst. La poudre de polyoléfine contient des particules possédant une morphologie pelucheuse. Le procédé de préparation de la poudre de polyoléfine est réalisé par la polymérisation par coordination d'oléfines-1 sur le précatalyseur Ziegler-Natta traité thermiquement activé par le cocatalyseur organo-alumineux.
