✦ Synopsis

Butadiene is polymerized by the catalyst system nickel diisopropylsalicytatei~ooron trifluoride etherate/butyl lithium to high cis-l,4-configuration. A description is given of the effects of (a) changing catalyst component ratios; (b) order of catalyst addition; and (c) change of solvent, on microstructure, molecular weight and conversion.
