    Abstract: Polyethers, preferably containing sulfone groups, are obtained by a multi-stage condensation process at from 100 DEG to 230 DEG C. from substantially equivalent amounts of bis-(4-hydroxyphenyl)-sulfone and a dichlorobenzene compound in a polar aprotic solvent in the presence of an anhydrous alkali metal carbonate, with or without the addition of a compound which forms an azeotrope.

    Abstract: A moulding based on a thermoplastic or duroplastic polymer, has a permanent anti-static finish, applied from a 1-20 wt.% soln. of the polymer, contg. 0.05-4 wt.% of a dissolved or dispersed, electrically conducting filler; the ratio by wt. of the polymer:filler in the soln. is 1-50 : 1.

    Abstract: Thermoplastic moulding compositions containing A) 4-94% by weight of a partly aromatic, partly crystalline copolyamide having a diamine content of less than 0.5% by weight, built up from (A1) 20-90% by weight of units derived from terephthalic acid and hexamethylenediamine, (A2) 0-50% by weight of units derived from epsilon -caprolactam, (A3) 0-80% by weight of units derived from adipic acid and hexamethylenediamine, (A4) 0-40% by weight of further polyamide-forming monomers, where the proportion of components (A2) or (A3) or (A4) or mixtures thereof is at least 10% by weight, B) 4-94% by weight of a polyolefin homopolymer or copolymer or a mixture thereof, C) 2-20% by weight of an adhesion promoter (coupling agent), D) 0-20% by weight of an impact-modifying polymer, E) 0-60% by weight of additives and processing assistants. %
