Abstract
Abstract Organoaluminum compounds of the formula ##STR1## in which A, B and C are each selected from alkoxy, aryloxy, alkylcarboxyl, arylcarboxyl, a dicarboxylic acid half ester, a dicarboxylic acid half amide, alkyl sulfate, aryl sulfonate, dialkyl phosphate, alkylaryl phosphate, diaryl phosphate, dialkyl-phosphite, alkylaryl phosphite, diarylphosphite, or oxymetal group of the formula OMA in which M is a divalent metal; a and b are 0, 1 or 2 with the proviso that a + b = 2; x is at least 2 and z is a polyfunctional group selected from organic polymers or polycondensation products, inorganic macromolecules and metals. The products are prepared by addition of a polyfunctional compound or metal to an excess of organoaluminum compound.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
The process for preparing a storage-stable fluid, moisture-sensitive compound of a formula selected from the group consisting of ##STR9## in which a polyfunctional compound of the formula H x Z is added to an excess of an organoaluminum compound of at least one formula selected from the group consisting of ##STR10## wherein A, B and C are each selected from the group consisting of alkoxy, aryloxy, alkylcarboxyl, arylcarboxyl, a dicarboxylic acid half ester, a dicarboxylic acid half amide, alkyl sulfate, aryl sulfonate, dialkyl phosphate, alkylaryl phosphate, diarylphosphate, dialkylphosphite, alkylaryl phosphite, diarylphosphite, and an oxymetal organic group of the formula OMA in which M is a divalent metal and A is as defined herein, a and b are each selected from 0, 1 and 2 and c is selected from 1, 2 and 3 with the proviso that a + b + c = 3, H x Z is a polyfunctional compound selected from the group consisting of pigments and fillers containing reactive hydroxyl groups, and x is the number of groups capable of reacting with said C.
Claim 2
Dependent Claim
