摘要
Catalyst systems (A) contain as active components, metallocene complexes of Gp. IV and Gp. V metals, an oligomeric aluminium oxide cpd. and an organic aluminium cpd. of formula (IV). R18, R19 = 1-15C alkyl, R20 = 1-15C alkyl, 1-4C alkoxy or halogen. Prepn. of polymers of 2-10C alkenes at 1-1000 bar and -50-300 deg.C using (A) and the resulting polymers are also claimed. ADVANTAGE - Use of (A) leads to lower levels of aluminium residue within the polymer prod.
