Date Feb. 22, 1996The novel blend comprises: (A) from 1 to 99% by weight of at least one thermotropic-liquid-crystalline polyester and/or polyesteramide and (B) from 1 to 99% by weight of at least one sulfoxide group-containing polymer, in each case based on the total weight SIGMA [(A)+(B)]. Component (B) is a linear and/or branched polymer having a mean molecular weight Mw in the range from 4,000 to 200,000 comprising recurring units of the formula [-F-S)c-(F-SO)d-], where F, independently of one another, are simple or para-, meta- or ortho-linked arylene systems having 6 to 18 carbon atoms, preferably phenylene, naphthylene or biphenylene, where the sum c+d is 1, with the proviso that d is always >/=0.70. Component (A) is a thermotropic liquid-crystalline polymer having a mean molecular weight Mw in the range from 10,000 to 200,000 g/mol and a transition temperature of >250 DEG C., and/or an amorphous thermotropic liquid-crystalline polymer having a mean molecular weight Mw of from 10,000 to 200,000 g/mol and a glass transition temperature of >160 DEG C.

    Abstract: Filter material and method of removing oxides of nitrogen from gases and liquids A filter material based on a polyarylenethioether with recurring units of the formula -¢(Ar1)n-X)!m-¢(Ar2)i-Y)!j-¢(Ar3)k-Z)!1-¢(Ar4)o-W)!p- (I) in which Ar1, Ar2, Ar3, Ar4, W, X, Y and Z independently of one another are identical or different, the indices n, m, i, j, k, l, o and p independently of one another are zero or integers 1, 2, 3 or 4, the sum of which is at least 2, Ar1, Ar2, Ar3 and Ar4 are arylene systems of 6 to 18 carbon atoms and W, X, Y and Z are divalent linking groups selected from -SO2-, -S-, -SO-, -CO-, -O-, -CO2-or alkylene or alkylidene groups of 1 to 6 carbon atoms, for removing oxides of nitrogen (NOx) from gases or liquids. Also claimed is a method of removing oxides of nitrogen, in which an NOx-containing gas or a liquid is brought into contact with the abovementioned filter material and a chemical reaction occurs. Nitrogen monoxide can likewise be removed by adding to the filter material oxidative inorganic or organic compounds having an electron potential of greater than or equal to 0.96 V.
