Hydrocarbylaluminoxanes, especially methylaluminoxane, having high catalytic activity in the polymerization of olefins are made in high yield and low gel content by impinging (1) a solution of a hydrocarbyl aluminum, e.g. trimethyl aluminum, in an inert solvent, e.g. toleune, with (2) a water dispersion in an inert solvent (e.g. toluene) in a T-shaped reactor such that the hydrocarbyl aluminum and water immediately react to form an aluminoxane solution which is promptly removed from the T-shaped reactor through its third arm. The water dispersion is formed by passing a solvent/water mixture through a static mixer which comprises a plurality of deflection vanes forming a tortuous path through the static mixer causing extremely turbulent flow. |
