From modified methylaluminoxanes (MMAOs) to isobutylaluminoxanes (IBAOs), we supply the world's largest range of modified aluminoxanes for use in single-site catalyst technology. This technology allows our company to provide precisely-tailored polymer properties and has revolutionized the polymer industry.

Our MMAOs contain modifiers, which provide superior stability for long-term storage. Modifiers also often provide excellent solubility in aliphatic hydrocarbons.

Due to the difficulty in producing and handling aluminoxanes, they are only offered as a hydrocarbon solution. Concentrations depend on properties of the aluminoxane, but solutions typically contain 7 wt% on soluble aluminum basis, corresponding to an aluminoxane concentration of about 15-19 wt%.

Our metal alkyls and organometallic specialties businesses are part of an extensive global network, allowing our modified methylaluminoxanes to be shipped to customers around the world.
