  • Process to prepare aluminoxanes
    Patent number: 10822356
    Abstract: Process to prepare alkylaminoxane by reacting, in the absence of solvent, 1 molar equivalent of alkylaluminium with 0.1 to 0.8 molar equivalent of a substituted allylic alcohol of the formula (I) wherein R1 and R2 are independently selected from aliphatic and aromatic hydrocarbon groups, and each R3, R4, and R5 is independently selected from aliphatic and aromatic hydrocarbon groups and a hydrogen atom.
    Type: Grant
    Filed: May 19, 2017
    Date of Patent: November 3, 2020
    Assignee: NOURYON CHEMICALS INTERNATIONAL, B.V.

  • Process to prepare aluminoxanes
    Patent number: 10323047
    Abstract: The present invention relates to a process to prepare alkylaluminoxanes by reaction of alkylaluminium with methacrylic acid or a conjugated unsaturated carbonyl-functional compound of the formula (I) wherein each R1 and R2 independently are an aliphatic hydrocarbon group, and R3 independently is the same hydrocarbon group as R1 and R2 or a hydrogen atom, and R4 isanaliphatic hydrocarbon group, a hydroxyl group 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.
