Abstract: Polymer mixts. (I) contain (A) 1-99 wt.% polyarylene sulphide(s) (PAS) and (B) 1-99 wt.% polyarylene sulphoxide(s) (PASO). Also claimed is a process for the prodn. of crosslinked or partly crosslinked PAS-contg. moulding materials by heating (partly) oxidised PAS contg. sulphoxide gps., or a mixt. or blend contg. PAS and PASO or oxidised PAS, at 280-400 (pref. 280-380) degrees C.

Abstract: A polyarylene sulphide foam has a density reduced by at least 50 % compared with the theoretical density of non-foamed material. In order to produce the polyarylene sulphide foam, polyarylene sulphoxide is subjected alone or mixed with one or several polyarylene sulphides to a thermal treatment at a temperature in a range from 250 to 400 DEG C.

Abstract: A moulding composition comprising (A) from 20 to 80% by weight of at least one polyarylene sulphide, (B) from 1 to 60% by weight of at least one mineral filler, (C) from 1 to 65% by weight of at least one surface-modified mineral filler and (D) from 0.01 to 0.4% by weight of at least one saturated, long-chain carboxylic acid ester (carboxylate), can be converted by injection moulding or extrusion into mouldings which have a high surface quality and isotropic properties. Metallisation of the mouldings proves to be durable, which favours use for lamps, in particular reflectors, and electronic functional parts.

Abstract: Polymer-based filter material, for removing NOx from gases and liquids by chemical reaction between (I) and NOx, consists of a polyarylene thioether (II) with recurring units of the formula -((Ar )n-X))m-((Ar )i-Y)j-(Ar )k-Z))l((Ar )o-W))p- (II); Ar = 6-18C arylene systems; W,X,Y,Z = divalent bridging gps., selected from -SO2, -S-, -SO-, -CO-, -O-, -CO2- or 1-6C alkylene or alkylidene gps., at least one being -S-; n,m,i,j,k,l,o,p = 0, 1, 2, 3 or 4; n+m+i+j+k+l+o+p = at least 2. The claims also cover the process for removing NOx with (I) and the use of (I) for making a filter for this purpose.
