ABSTRACT:
A new catalyst and method of making polymers therewith and the process of preparing the catalyst in which the catalyst is prepared by dispersing on a finely divided carrier material, particularly a difficultly reducible inorganic support such as silica, a reaction product of (1) a chromium carboxylate reactant and (2) an organic nitrogen cmpound reactant capable of forming a complex such as a chelate with the chromium and activating the resulting mixture by heating at an elevated temperature in a non-oxidizing atmosphere.
