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, an organic chromiun (II) or (III) salt or derivative of a carboxylic acid or an N-substituted carboxylic acid or a nitrogen-heterocyclic carboxylic acid and activating the resulting mixture by heating at an elevated temperature in a non-oxidizing atmosphere.
