An improved process is provided herein for the preparation of immobilized transition metal catalysts containing up to about 60 wt. % bound transition metal. These catalysts are obtained by heating a hydroxylic support with an excess of a transition metal alkoxide in an inert hydrocarbon and in the presence of water.

Supported transition metal catalysts and process for their preparation

Ester products are obtained using an immobilized supported transition metal catalyst. Esters and polyesters having improved color and containing virtually no residual metal catalyst can be obtained with this process either by direct esterification or by ester interchange.
