ABSTRACT:
A poly(-N-alkyliminoalane) having the composition (HAlNR).sub.n, wherein R represents an aliphatic, cycloaliphatic, aromatic or alkyl-aromatic group, and n is a number in the range of 3 to 50, is prepared by directly reacting metallic aluminum with a primary amine having the formula H.sub.2 NR, wherein R has the meaning given above, in the presence of hydrogen at a pressure in the range of from 1 to 1000 kg/cm.sup.2 and at least a stoichiometric quantity of aluminum, at a temperature in the range of from room temperature to the dissociation temperature of the end product, and in the presence of a promoter such as a small quantity of the poly(-N-alkyliminoalane) constituting the end product of said reaction.
