Abstract

The catalytic system Co/methylaluminoxane/tert-butyl chloride has been studied and optimized for the polymerization of 1,3-butadiene to high cis-1,4-polybutadiene. The ratio of the individual catalyst components was investigated to achieve maximum conversion, stereoregularity, and molecular weight. It was found that the specific order of addition of catalyst components tothe feedstock and aging time therein has critical influence in the polymerization reaction. This can be attributed to the rate of chlorinating the aluminoxane and the stability of the active catalyst sites obtained. (C) 1999John Wiley & Sons, Inc.
