ABSTRACT:
Silica xerogels having pore volumes greater than about 2.0 cc/g., the major portion of which volumes are provided by pores having pore diameters ranging from 300 to 600 A, and surface areas ranging from 200 to 500 m.sup.2 /g. Xerogels having such cumulative pore volume, pore diameter distribution, and surface area characteristics are useful as supports for stereospecific catalysts for particle form olefin polymerization reactions effecting the production of low molecular weight, high melt index polyolefins.
