    摘要： A polymer composition especially suitable for producing fibre-reinforced structures having advantageous fracture toughness comprises a polyarylsulphone component and a thermoset resin component, each of which components is present at least partly as a phase continuous in at least one dimension. Preferred polyarylsulphones contain repeating units (PhSO.sub.2 Ph).sub.n and (Ph).sub.a linked through ether and/or thioether, where Ph is phenylene, n=1 to 2 and a=1 to 3; and such polyarylsulphones having amino end groups are provided as new compounds. The compositions can be made by spinodal decomposition of a mixture of the polyarylsulphone and a thermoset resin precursor.

    摘要： A coated polyester film suitable for producing polyester/polyolefin laminates consists of biaxially oriented poly(ethylene terephthalate) film coated with a cross-linked styrene copolymer by deposition from an aqueous coating composition which comprises (A) a copolymer containing 50-75 mol % of styrene units and 25-50 mole % of comonomer units providing carboxylic groups (10-50 mole %) and alkyl carboxylate groups (20-50 mole %) and (B) a melamine/formaldehyde cross-linking agent. The styrene copolymer (A) is preferably a water-soluble copolymer of styrene and maleic anhydride partially converted into butyl ester and partially neutralized with ammonia, and the cross-linking agent (B) is conveniently hexamethoxymethylmelamine. The polyolefin layer in the laminates produced may in particular be of low-density polyethylene.

    摘要： An aromatic polymer comprises divalent aromatic units linked through oxygen, characterized in that some at least of those units are or contain aromatic rings free of electron-withdrawing groups and in that at least one of such rings carries at least one nitrogen radical linked to a nuclear carbon atom by a nitrogen-carbon bond.Preferably it consists to the extent of at least 75 mol percent by the repeating units:O--Ph'--O--Ph--A--Ph Ialone or in combination withO--Ph--A--Ph--O--Ph--A--Ph IIwherePh is paraphenylene;Ph' is phenylene, at least some of groups Ph' carrying a nitrogen radical;A is SO.sub.2 or CO; andthe As can be the same or different in the polymer chain.A process is provided which comprises nitrating a parent polymer and optionally reducing nitro groups to amino followed optionally by substitution of amino.
