SUPPORTED IONIC LIQUIDS OR ACTIVATING SUPPORTS

摘要

The present invention relates to the covalent anchorage of non-coordinating anions on mineral supports to prepare supported ionic liquids and to their use as activating supports for the polymerisation of ethylene and alpha-olefins. The invention also discloses the concomitant covalent anchorage of zwittehonic systems containing both the non-coordinating anion and the counter cation parts of the ionic liquids and of the activating supports.
