ABSTRACT:
Fine, pure, boehmite alumina crystallites are peptized, partially precipitated and phosphated, hardened, and dried to form a zerogel. The alumina can be impregnated with a chromium compound. The chromium-containing catalyst is activated by calcination. The activated catalyst can be used as a polymerization catalyst to polymerize mono-1-olefins.
