IMPROVED ALUMOXANE, METHOD FOR ITS PREPARATION AND POLYMERISATION PROCESS USING SUCH ALUMOXANE

摘要

The invention provides a method of subjecting an alumoxane to a secondary hydrolysis which comprises: hydrolysing an alumoxane starting solution which is macroscopically substantially clear and has a viscosity approximating that of the solvent and a content of a Al containing compounds of at least 3 wt % in such a manner as to produce a substantially stable, opaque suspension having a viscosity at least 0.1 centistoke preferably 0.2 centistoke above that of the starting solution.
