Abstract (en)
[origin: DE19832446A1] Conjugated dienes are copolymerized with vinyl-aromatic compounds in the presence of catalysts containing: (a) rare earth metal compound(s), (b) cyclopentadienyl compound(s) and (c) organoaluminum compound(s), (or (a) and (c) only). Conjugated dienes are copolymerized with vinyl-aromatic compounds (VAC) at -30 to +100 deg C in the presence of VAC using catalysts containing: (a) rare earth metal compound(s), (b) (optional) cyclopentadienyl compound(s) and (c) organoaluminum compound(s), The mole ratio of a:b:c is 1:(0.01-1.99):(0.1-1000) or (a:c) is 1:(0.1-1000). 1 micromole to 10 mmoles (a) and 50-2000 g VAC are used per 100 g diene.
