    Abstract: Fully aromatic thermotropic polyesters are based on (A) from 30 to 60 mol % of 4-hydroxybenzoic acid, (b) from 20 to 35 mol % of a mixture of (B1) terephthalic acid and (B2) isophthalic acid, the molar ratio of B1 to B2 being from 1.04:1 to 19:1, and (C) from 20 to 35 mol % of a mixture of (C1) hydroquinone, (C2) 4,4'-dihydroxydiphenyl and (C3) from 0.5 to 5 mol % of (C31) 2,7-dihydroxynaphthalene and/or (C32) 1,3-dihydroxybenzene and/or (C33) and aromatic dihydroxy compound of the general formula I (I) where X is -CH2-, -C(CH3)2-, -S-, -SO2-, -O- or -CO-, and/or (C34) a compound of the general formula II (II) where Y is NH2 or OH, the molar ratio of C1 to C2 being from 0.1:1 to 2.67:1 and the molar ratio of B to C being from 0.9:1 to 1.1:1.

    Abstract: The invention relates to a thermoplastic moulding composition containing A from 20 to 80% by weight of a thermoplastic polysulphone resin (polyarylene-polyether-polysulphone), B from 10 to 60% by weight of a polycarbonate, C from 5 to 50% by weight of at least one copolymer based on c1) at least one vinylaromatic monomer from the group consisting of styrene, alpha -methylstyrene and p-methylstyrene, or mixtures thereof, and c2) acrylonitrile, and D from 5 to 50% by weight of at least one graft copolymer comprising, in each case based on C, d1) from 50 to 90% by weight of at least one elastomer (rubber) and d2) from 10 to 50% by weight of at least one shell grafted onto the elastomer, is characterised in that the copolymer C used contains, based on C, from 88 to 73% by weight of the vinylaromatic monomer c1) and from 12 to 27% by weight of acrylonitrile c2) in copolymerised form, and the viscosity indices are in the range from 50 to 100, and that furthermore, a graft copolymer D having a mean particle size in the range from 80 to 500 nm is used whose elastomer d1) contains, in copolymerised form, d11 at least 80% by weight of butadiene and d12 from 0 to 20% by weight of styrene and/or acrylonitrile, and whose shell c2 contains, based thereon, d21 from 90 to 10% by weight of styrene and d22 from 10 to 90% by weight of methyl methacrylate. The moulding composition is used for the production of mouldings.
