DICOPS CONTAINING ACETYLENIC SUBSTITUENTS

摘要

An activator for olefin polymerization catalysts is disclosed. One aspect of the activator is that it comprises a group-13 central atom connected to at least one fluorinated aryl ring that is itself substituted with a silyl acetylenic group. Some embodiments employ a neutral activator and others employ the activator as an anion coupled with a ligand-abstracting cation. These activators are discrete molecules.
