    Abstract: Thermoplastic aromatic polyether amide in which the structure comprises the recurring units of the formulae… -CO-Ar-CO- (A) and… -NH-Ar-O-Ar-X-Ar-O-Ar-NH- (b> in which Ar is a divalent, unsubstituted or substituted aromatic radical having 6 carbon atoms whose bonds are in the p-position, and X is a 2,2-propylidene bond. The polyether amide has a Staudinger index [ eta ] in a range from 50 to 750 cm /g and a glass-transition temperature of above 200 DEG C, and a process for its preparation. The preparation of the polyether amide is carried out by a low-temperature solution, solid, interface or melt condensation process. … The polyether amide is used to produce moulded articles in the form of filaments, wires, films and other mouldings produced by extrusion, press moulding or injection moulding of the dry, pulverulent polyether amide or by processing solutions of the polyether amide.

    Abstract: The structure of the aromatic copolyether amide which can be processed as a thermoplastic comprises recurring units of the formulae -CO-Ar1-CO- (A), -NH-Ar1-O-Ar1-X-Ar1-O-Ar1-NH (B) and -NH-Ar2-NH- (C) in which Ar1 denotes a divalent, unsubstituted or substituted aromatic radical having 6 carbon atoms which is linked in the p-position, X represents a 2,2-propylidene link and Ar2 is identical with Ar1 or is Ar1 which is linked in the m-position, or is the -Ar1-Z-Ar1- group in which Z is a direct bond or is a radical -CH2-, -C(CH3)2-, -SO2-, -CO-, -O-, -CH=CH-, -CO-NH- or -O-Ar1-O- or the radical in which R represents hydrogen or a branched or unbranched alkyl radical having 1-4 carbon atoms. The proportion of units (A) and of the sum of units (B) and (C) is each 100 mol-%, the proportion of units (C) being up to 50 mol-% and, if Z represents -SO2-, up to 75 mol-%. The Staudinger index [ eta ] of the copolyether amide is in the range from 50 to 1000 cm3/g, and the value of the glass transition temperature is above 200 DEG C. The copolyether amide is prepared by a low-temperature solution, solid, interface or melt condensation process. The moldings produced therefrom in the form of filaments, wires, films and other moldings are obtained by processing the pulverulent copolyether amides or their solutions.

    Abstract: Polymer alloys contain (A) at least one cycloolefin polymer and (B) at least one polyarylether ketone, the quantity of (A) amounting to 1 to 99 wt% and the quantity of (B) amounting to 99 to 1 wt%, whereas both quantities added together form 100 wt% of the whole alloy. Such polymer alloys are useful as matrices for composite materials or for producting mouldings.
