    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.

    Abstract: Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A containing reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if required together with a heat-stable thermoplastic polymer B which does not contain any reactive groups, is applied onto reinforcing fibers, the resulting semi-finished product is shaped, and the plastic matrix in the molding obtained is crosslinked so that there is virturally no increase in its glass transition temperature although the amount of soluble material is decreased to less than 60%, determined by extraction in boiling dichloromethane for one hour.
