摘要： A new polymer composition comprises an aromatic polyetherketone or mixture thereof containing the repeating units--O--Ph--O--Ph--CO--Ph-- Iand--O--Ph--Ph--O--Ph--CO--Ph-- II(where Ph is phenylene) in the relative molar proportions I:II of 95:5 to 60:40 and 5-80% w/w of a fibrous reinforcing agent. It is suitable for producing shaped articles of high damage tolerance by hot fabrication followed by slow cooling.

摘要： A method of increasing the molecular weight of a poly(aryl ether) comprising providing a mixture of (1) at least one polyaryl ether comprising polymer chains having end groups selected from groups of formula--Ar--X,preferably--Y--Ar--X and --Ar--OXand (2) a reagent having nucleophilic activity selected from (a) alkaline salts of Group I or Group II metals (as hereinafter defined) and (b) reagents have radicals --X and --OZ, reactive respectively with the end groups --Ar--OZ and --Ar--X, wherein when the end group is --Ar--X the reagent is either a difunctional reagent having either both end groups in the form of reactive --OZ groups or a difunctional reagent having one reactive --OZ group and one reactive --X group and when the end group is --Ar--OZ the reagent is a difunctional reagent having reactive end groups --X, and wherein Ar represents an arylene radical, preferably a phenylene radical, X is a monovalent radical capable of nucleophilic diplacement from Ar, preferably selected from halogen, nitrile (CN) or nitro (NO.sub.2) radicals, Y is an electron withdrawing group, which when Ar is phenylene is positioned ortho or para, preferably para to the X group and when Ar is not phenylene, X and Y are attached to the Ar group by parallel and oppositely directed bonds and Z is a univalent metal, and heating the mixture to a temperature above the melting point of the polymer until a desired increase in molecular weight has occurred. The method is useful for preparing fibre reinforced compositions and particularly for the process of impregnating fibre structures.

摘要： The present invention relates to a process for the preparation of 4,4'-difluorobenzophenone. 4,4-difluorobenzophenone may be prepared by diazotization of 4,4'-diamino-diphenylmethane in anhydrous or concentrated aqueous hydrogen fluoride, decomposition of the diazonium fluoride thus produced to yield 4,4'-difluoro-diphenylmethane and oxidation of 4,4'-difluoro-diphenylmethane to yield 4,4'-difluorobenzophonone.Thus, according to the present invention, there is provided a process for the preparation of 4,4'-difluorobenzophenone which comprises the following steps:(1) diazotization of 4,4'-diamino-diphenylmethane in anhydrous or concentrated aqueous hydrogen fluoride to yield a solution of a corresponding diazonium fluoride; and(2) (i) thermally decomposing the diazonium fluoride in the solution thus produced to yield 4,4'-difluoro-diphenylmethane and (ii) subsequently oxidizing the 4,4'-difluoro-diphenylmethane to yield 4,4'-difluorobenzophenone.
