Abstract
A method comprising contacting a support material with a transition metal compound to produce a mixture; thermally treating the mixture in the presence of oxygen at a temperature in a range of from about 100° C. to about 500° C. for a period of from about 1 hour to about 10 hours, wherein at least a portion of the transition metal sublimes onto the support material to produce a support material comprising a dispersed transition metal; and thermally treating the support material comprising the dispersed transition metal in an oxidizing atmosphere at a temperature in a range of from about 550° C. to about 900° C. for a period of from about 1 hour to about 10 hours to produce a polymerization catalyst.
