ABSTRACT:
A catalyst having a high pore volume, high surface area porous silica support and a non-metallocene, Ziegler-Natta catalytic component incorporated on the silica support is provided for the production of polyolefins from .alpha.-olefins. The porous silica support is made up of silica gel particles having an average surface area of about 600 to about 800 m.sup.2 /g of silica and an average pore volume of about 2.5 to about 4.0 ml/g of silica. Preferably, the silica particles have an average surface area of about 650 to about 750 m.sup.2 /g of silica and an average pore volume of about 2.75 to about 3.25 ml/g of silica. Even more preferably, the silica particles have an average surface area of about 700 m.sup.2 /g of silica and an average pore volume of about 3.0 ml/g of silica. The catalytic component comprises a complex product of a transition metal halide and a metal alkyl which excludes cyclopentadienyl rings.
