Oligomeric iminic derivatives of aluminum hydride and method for their preparation

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.
