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, dialkylphosphite, 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.
