Abstract: A process for the preparation of a thermoplastic moulding composition comprising 80 - 50% by weight of a hard matrix of an anionic polymerised vinylaromatic compound and 20 - 50% by weight of a soft phase uniformly distributed in the hard matrix, in each case based on the sum of the hard matrix and the soft phase, characterised in that, in a first step, an elastomeric block copolymer based on a vinylaromatic compound and an alkadiene is polymerised anionically in a weight ratio of 5:95 to 55:45, the living ends of the chain are optionally blocked, and, with a re-addition of an anionic initiator and with stirring, the vinylaromatic compound is polymerised in the presence of the block copolymer and the living ends of the chain are finally blocked again.

Abstract: A process for the preparation of graft copolymers (I) by anionic polymerisation of a polymer (A) containing an anionic chain end and a polymer (B) containing a nitrile group in a solvent is claimed. Preferably (A) is a vinyl aromatic based polymer, a block copolymer consisting of a block of vinyl aromatic monomers and a block of conjugated dienes, preferably polystyrene or polystyrene-polybutadiene. (B) is a copolymer of styrene and acrylonitrile. (B) is titrated with a solution of a organometallic compound, preferably s-butyllithium before mixing with (A) in ethyl benzene.

The relative proportion of 1,2 bonds of the polydiene in relation to the sum of 1,2 and 1,4 cis/trans-bonds is under 15 %, process for their production by anionic polymerisation by means of lithium alkyl in a non-polar solvent in the presence of a soluble potassium salt and their use for the production of mouldings.
