Abstract (en)

[origin: DE19832442A1] Conjugated dienes are polymerized at -30 to 80 deg C in presence of: (A) catalysts comprising: (a) vanadium compounds; and (b) aluminoxanes in a mol ratio of (a):(b) = 1:(10-1000); and (B) aromatic vinyl compounds (AVC); using 1 micro mol to 10 mmols component (a) and 10-2000 g AVC per 100 g monomer used.
