If the functional units (C) are derived from a cyclic olefin, exactly two adjacent C atoms of this gp. are built into the main polymer chain. Also claimed are (i) the prodn. of (I) by reacting a double bond-contg. COC (II) in inert solvent with ozone; (ii) coating materials contg.

    Abstract: A semipermeable membrane is described which comprises a homogeneously miscible polymer blend of an aromatic polyamide and polyvinylpyrrolidone. The aromatic polyamide is in particular formed of recurrent units of the formula I: (I) wherein E1 and E2 are identical or different and are selected from the groupings -AR1-, and -AR1-X-AR2, where AR1 and Ar2 are the same or different 1,2-phenylene, 1,3-phenylene or 1,4-phenylene groups which may be substituted by (C1-C6)-alkyl, (C1-C6)-alkoxy, -CF3 or halogen and X denotes a) a direct bond or one of the following divalent groups: -O-, -C(CF3)2-, -SO2-, -C(R1)2-, with R1 being hydrogen, (C1-C6)-alkyl or fluoroalkyl having from 1 to 4 carbon atoms in the alkyl group or -Z-AR1-Z-, where Z is one of the groups -O- and -C(CH3)2 or -O-Ar1-Y-Ar2-O-, where Y has the meaning given under Xa) above. The membrane has pronouned hydrophilic properties and is moreover stable to hydrolyzing agents and oxidants and to the action of heat. It is also resistant to organic solvents and microorganisms and exhibits low adsorption of proteins. A process for producing the membrane and a process for modifying the retention capacity thereof are also described. The membrane is produced by spreading a solution of the homogeneously miscible polymer blend on a planar substrate and precipitating the blend. Retention capacity is modified by heat treatment.

    Abstract: WO 92/09648 PCT/EP91/02112 of the disclosure: Thermoplastically processable aromatic polyether amide Thermoplastically processable aromatic polyether amide of the formula (I) (I) in which the symbols Ar, Ar', Ar1, Ar2, R, R', Y, x, y and z have the following meanings: Ar is a divalent, substituted or unsubstituted, aromatic or heteroaromatic radical or a group -Ar*-Q-Ar*-in which Q is a bond or an -O-, -C(CH3)2, -CO-, -S-, -SO- or -SO2-bridge and Ar* is an aromatic radical. The carbonyl groups of the Ar radical are on non-adjacent ring carbon atoms. A is up to three different radicals. Ar' has the meaning given for Ar or is an Ar-Z-Ar group. In this case, Z is a -C(CH3)2- or -O-Ar*-O-bridge. Y is a -C(CH3)2-, -SO2-, -S- or a -C(CF3)2-bridge and has up to two different meanings in the same polymer. Ar1 and Ar2 are identical or different from one another and are each a substituted or unsubstituted para- or meta-arylene radical. The sum of the mole fractions x, y and z is one. The sum of x and z may not be equal to y and x can assume the value zero. In a preferred embodiment, z is greater than x.
