    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".sub.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.
