Method for preparation of oligomeric iminic derivatives of aluminum

摘要

There are disclosed oligomeric aluminum hydride iminic derivatives, to be employed as catalysts in polymerization processes and which are prepared by causing alkali-metal or alkaline-earth-metal alanates to react with a primary amine which contains a group of the type -X-R''m, wherein X is a nitrogen atom or an oxygen atom and m is equal to the valence of X minus one. The compounds have a trimeric or a tetrameric "open cage" spatial configuration.
