Abstract: The invention relates to mixtures containing linear block copolymers consisting of vinyl aromatic monomers and dienes, of structure (I) S 1 -B 1 -S 2 and (II) S 3 -B 2 -S 4 , wherein S 1 represents a block of vinyl aromatic monomers having a number average molar mass M n of between 40,000 and 100,000 g/mol; S2, S3 and S 4 respectively represent blocks of vinyl aromatic monomers having a number average molar mass M n of between 5,000 and 20,000 g/mol; and B 1 and B 2 respectively represent blocks of dienes or copolymer blocks of dienes and vinyl aromatic monomers having a number average molar mass M n of between 15,000 and 40,000 g/mol. The ratio of the block copolymers (I)/(II) is between 0.6 and 2.

Abstract: A method for the production of impact-resistant moulding materials by anionic polymerization of vinyl aromatic monomers in the presence of rubber in a continuously through-flown reactor cascade consisting of at least two reactors. The vinyl aromatic monomers are fed to the reactors of the reactor cascade in partial flows and an anionic initiator and rubber are fed to at least the first reactor. The reactor cascade consists of backmixed reactors.

Abstract: A process for the homopolymerization of vinyl aromatic monomers or copolymerization of vinyl aromatic monomers and dienes comprises polymerization of the monomers in the presence of at least an organoalkali metal, an organomagnesium compound and an organoaluminum compound. Independent claims are included for: (i) an initiator composition comprising an organoalkali metal, an organomagnesium compound and an organoaluminum compound, whereby the molar ratio of magnesium to the alkali metal is 0.2-3.8 and the molar ratio of aluminum to the alkali metal is 0.2-4; (ii) a process for the preparation of an initiator composition by dissolving the organometallic compounds in inert hydrocarbons and allowing the mixture to mature at 0-120 deg C for at least 5 minutes.

Abstract: Continuous anionic (co)polymerisation of styrene or diene monomers with alkali metal alkyl (I) as initiator is carried out in the presence of an alkyl or aryl of an at least divalent metal as retarder (II). Also claimed are (a) an initiator containing (I) and (II); (b) a solution of the initiator in a (cyclo)aliphatic hydrocarbon; and (c) styrene polymers obtained by this process.
