    Abstract: The invention relates to a method for producing 4,4'-dihalogendiphenylsulfone by reacting halogenated benzene with 4-halogenphenylsulfonyl chloride in a liquid phase at high temperature, in the presence of a solid catalyst having acid centers. The method is characterized in that the reaction of 4halogenphenylsulfonyl chloride with formula (I), in which X is chlorine, bromine or fluorine, with chlorobenzene, bromobenzene, or fluorobenzene, is carried out in the presence of a catalyst which is selected from one of the following groups: K1) catalysts consisting of essentially stratified silicates not having Lewis acids and having proton-saturated negative layer loads, or containing these as a basic component; K2) catalysts consisting of zeolites in the acid H form, or containing these as a basic component; and K3) catalysts consisting of mixed oxides having acidic centres, or containing these as basic components. The mixed oxides consist of a combination of (a) titanium, circonium, hafnium, tin, iron or Cr(III) oxides on the one hand, and (b) vanadium, chromium(VI), molybdenum, wolfram or scandium oxides on the other hand; or the mixed oxides are sulfatized or phosphatized oxides of the group (a), and said mixed oxides are calcined after combination, at temperatures of 450 to 800 ~C.

    Abstract: Molding materials based on polyaryleneethersulfones having good impact toughness and notched bar impact toughness are new. The molding materials are obtained from: (A) a polyaryleneethersulfone (PAES) (a1) of OH content 0.005-5 wt.% and having structural units (I); or (a2) having structural units (II); or (a3) with structural units (I) and (II), where the PAES (a1) to (a3) preferably also has the structure (IIIa); or (IIIb); or mixtures of (IIIa) and (IIIb); (B) at least one rubber based on (wt.%): (b1) ethylene (49.9 - 98.9), (b2) (meth)acrylic acid ester(s) (1 - 50), (b3) glycidyl (meth)acrylate(s) (0.1 - 20), and (b4) maleic acid anhydride (0 - 20); (C) at least one filler (0 - 60); and (D) at least one additive (0 - 40). Independent claims are included for: (1) molding materials in which the PAES (a1), (a2), or (a3) contains 0.03 - 2 wt.% OH groups; (2) molding materials in which component B is a rubber based on (wt.%): (b1) ethylene (59.85 - 94.85), (b2) a (meth)acrylic or ester or their mixtures (5 - 40), (b3) a glycidyl (meth)acrylate or their mixtures (0.15 - 15); (3) a molded body, film, or fiber obtained from the above molded materials.
