ABSTRACT:
An alumina-containing material is phosphated with mono- and dialkylphosphate esters. These partial phosphate esters are produced by a solvolysis reaction of a phosphorus compound and an alcohol. The phosphated alumina-containing material, when combined with a transition metal, such as chromium, can be used as a polymerization catalyst system to polymerize mono-1-olefins.
