Blends based on copolyarylene ether sulfones

Molding compositions based on polyaryl ethers A, are obtainable by reacting polyaryl ethers I with repeating structural elements ##STR1## or derivatives thereof substituted by C.sub.1 -C.sub.6 -alkyl, alkoxy, aryl, chlorine or fluorine in the nucleus, where X and Z, independently of one another, are each --SO.sub.2 --, --O--, --S--, &gt;C.dbd.O a chemical bond or --CRR'--, R and R' are each hydrogen, C.sub.1 -C.sub.6 -alkyl or alkoxy, R' is also aryl or fluoro- or chloro-substituted aryl, with the proviso that X and Z are not both --O--, with a reactive compound which, besides a C--C double or triple bond, contains one or more carbonyl, carboxylic acid, carboxylate, acid anhydride, amide, imide, carboxylic ester, amino, hydroxyl, epoxy, oxazoline, urethane, urea, lactam or halobenzyl moieties.

Impact modifying rubber and partly aromatic copolyamides

Thermoplastically re-formable plastic sheets with flameproofing means, characterized by a core layer 1-10 mm thick comprised of polyether sulfone or a similar thermoplastic, which core material has a content of at least 0.5 wt. %, preferably at least 2 wt. %, of a flame-protective additive, such as boron trioxide; and said sheet or plate further characterized by outer layers, firmly adhering to and covering the two faces of the core layer, at least 0.05 mm thick and comprised of a thermoplastic having a lower proportional content of the flame-protective additives than the core layer; are particularly useful for interior structures in passenger conveyances, such as airplanes.

Partly aromatic copolyamide of reduced triamine content

Free-flowing granules of thermoplastic elastomers are obtained by applying a finely divided mineral powder, namely a silicate from the group comprising wollastonite, kaolinite or mica, in an amount of from 0.005 to 0.5%, based on the amount of elastomer, to the surface of the granules.
