Abstract
Alpha-olefin polymerization catalysts are prepared by heating a solid porous carrier having reactive OH groups in the atmosphere of an oxygen-containing gas. The resulting catalysts exhibit higher productivity and produce ethylene polymers or ethylene/C.sub.3 -C.sub.10 copolymers having higher bulk density than similar catalysts prepared with the carriers heated in an atmosphere of nitrogen.
