Abstract

1508048 Polyiminoalanes SNAMPROGETTI SpA 19 June 1975 [1 July 1974] 26213/75 Heading C3R The invention comprises a polyiminoalane having the general formula in which R is an aliphatic, aromatic or cycloaliphatic hydrocarbyl radical, H is hydride hydrogen, Y is a halogen atom, k is from 2 to 50, i is greater than zero, j # 0 and the ratios h : k and (i+j) : h are both greater than 1 : 1. The polymers are obtained by reacting an oligomer polyiminolane having one of the general formulae in which X and Y, which can be the same or different, represent hydrogen or halogen atoms directly bound to aluminium, n is an integer not more than 10, the sum (x + y) is an integer not more than 10, y is an integer of from 1 to 10, R is an aliphatic, aromatic or cycloaliphatic hydrocarbyl radical, and the number of halogen atoms in an oligomer (b) is not more than x + 2y, the rest of the moieties X and Y in the oligomer (b) up to a total of x+2y being constituted by hydride hydrogen atoms with an alkali or alkaline earth metal alanate or an aluminium hydride complex in a solvent medium. The products may be used in catalysts for the polymerization of olefinically unsaturated compounds. In examples the oligomers are reacted with lithium aluminium hydride, sodium aluminium hydride and a complex of aluminium hydride and diethyl ether; the products are used with titanium trichloride and with titanium tetrachloride to catalyse the polymerization of ethylene and of isoprene.
