Abstract
The present invention relates to a process to prepare alkylaluminoxanes by reaction of alkylaluminium with a substituted allylic alcohol of the formula wherein each R1 and R2 independently are an aliphatic or aromatic hydrocarbon group, and R3, R4, and R5 each independently may be the same hydrocarbon group as R1 and R2 or a hydrogen atom in the presence of an inert organic solvent. Additionally, it relates to the alkylaluminoxanes obtainable by the above process and their use.
