ABSTRACT:
Aluminum orthophosphate is prepared by combining a source of phosphate ions with an aluminum salt to form a concentrated mass, combining with sufficient neutralizing agent to partially neutralize, and aging until gellation occurs. The resulting aluminum phosphate is particularly suited for use as a base for a chromium olefin polymerization catalyst.
