ABSTRACT:
Supported catalyst compositions incorporating preformed materials comprising the reaction product of (1) organoborate compounds such as trialkyl borate, and (2) chromium trioxide. Typical supports constitute an inorganic material of moderate to high surface area, especially a high pore volume (greater than about 1.96 cc/g) silica xerogel. The supported catalysts are utilized alone or in conjunction with other catalytic ingredients such as organometallic and/or organo non-metallic reducing agents for the polymerization of 1-olefins.
