Abstract: A filter material based on a polyarylene thioether having repeating units of the formula--[(Ar.sup.1).sub.n --X)].sub.m --[(Ar.sup.2).sub.i --Y)].sub.j --[(Ar.sup.3).sub.k --Z)].sub.l --[(Ar.sup.4).sub.o --W)].sub.p --(I)in which Ar.sup.1, Ar.sup.2, Ar.sup.3, Ar.sup.4, W, X, Y and Z, independently of each other, are identical or different, the indices n, m, i, j, k, l, o and p, independently of each other, are zero or integers 1, 2, 3 or 4, their sum being at least 2, Ar.sup.1, Ar.sup.2, Ar.sup.3 and Ar.sup.4 are arylene systems having 6 to 18 carbon atoms, and W, X, Y and Z are divalent linking groups, selected from --SO.sub.2 --, --S--, --SO--, --CO--, --O--, --CO.sub.2 --, or alkylene groups or alkylidene groups having 1 to 6 carbon atoms is suitable for removing ozone from gases or liquids. The removal proceeds quantitatively, no volatile products being formed.

Abstract: Mixtures of liquid crystalline copolymers, polyether imides and compatibilizers and use thereof.Mixtures of at least one A) liquid crystalline copolymer, at least one B) polyether imide and at least one C) compatibilizer where the proportions of components A) and B) are each from 5 to 95 % by weight, based on the sum total of the two components, and the proportion of the compatibilizer C) is from 0.5 to 10 % by weight, based on the mixture of A) and B), have improved breaking strength and extension values.They are therefore highly suitable for producing molded articles or for use as matrix material for composites.
