Abstract (en)
[origin: DE19832455A1] Conjugated dienes are polymerized at -30 to 80 deg C in the presence of: (A) catalysts comprising: (a) cobalt compounds; (b) organoaluminum compounds; and (c) modifiers; and (B) aromatic vinyl compounds (AVC), using 1 micromole to 10 mmoles component (a) and 10-2000 g AVC per 100 g monomer used. The catalyst components are used in a mole ratio (a):(b):(c) of 1:(10-1000):(0.1).
