    Abstract: Polymers of vinylaromatic cpds. are prepd. at 0-150 deg C, in presence of a catalyst system comprising (A) at least 2 different metallocene complexes and (B) a cpd. forming metallocenium ions. Pref. the aromatic cpds. have formula (I) (where R = H (pref.) or 1-4C alkyl; R -R = H (pref.), 1-12C (1-4C) alkyl (pref.), or halogen (pref. Cl), or 2 adjacent gps. together form a 4-15C (4-12C) cyclic gp., or Ph, biphenyl, naphthalene or anthracene). The components are metallocene complexes formula (II) (where R -R = H, 1-10C alkyl, 5-7C cycloalkyl (opt. carrying 1-6C alkyl gps. as substits.), 6-15C aryl or arylalkyl, or 2 adjacent gps. form together 4-15C cyclic gps., or Si(R )3; R = 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl; M = metal or 3rd-6th sub-gps. or of the lanthanide series (pref. metal of 4th sub-gp.); Z -Z = H, halogen (Pref.), 1-10C alkyl (pref.), 1-10C alkoxy (pref.), 6-15C aryl or 1-15C aryloxy; z1-z5 = 0-5; z1+z2+z3+z4+z4+z5 = valency of (M - 1)). (B) The components are open-chain or cyclic alumoxan cpds. of formulae (R )(R )Al-(O-Al(R ))mR (III) or (IV) (where R = 1-4C alkyl; m = 5-30). The polymers are used to produce mouldings (claimed). Use is esp. in electrical and high temp. resistant applications. A simple process gives syndiotactic polymers with wide distribution of mol.wt. The polymers have mol.wt. 10000-10000000 (50000-1000000) and Mw/Mn of 5-100.

    Abstract: A process for producing polymers of vinyl aromatic compounds at temperatures in the 0 to 150 DEG C range in the presence of metallocene complexes as catalysts, in which polymerisation takes place at a pressure of 5 to 300 bar in the presence of aliphatic C1-C4 hydrocarbons and the co-catalyst used is a co-ordination complex compound selected from the group of strong, neutral Lewis acids, ionic compounds with Lewis acid cations and ionic compounds with Brönsted acids as cations.
