Abstract

1348630 Aromatic polymers IMPERIAL CHEMICAL INDUSTRIES Ltd 16 July 1971 [19 Aug 1970 19 May 1971] 39931/70 and 15792/71 Heading C3R Aromatic polymers having recurring units of the formula -Ar-Q- are prepared by heating an alkali metal fluoride with an activated halophenol or halothiophenol of the formula X-Ar-QH and/or a substantially equimolar mixture of an activated dihalobenzenoid compound of the formula X-Ar-X and a dihydric phenol or thiophenol of the formula HQ-Ar-QH in which Ar and Q are respectively a bivalent aromatic residue and an oxygen or sulphur atom and may vary from unit to unit in the polymer chain and X is a halogen atom, the amount of alkali metal fluoride being such that together with any of the X atoms that are fluorine the total number of fluorine atoms in the reaction system is at least twice the number of the -QH groups in the system, the halogen atoms in the halophenol, halothiophenol and dihalobenzoid compound being activated by an electron attracting group ortho or para to the halogen atoms. The alkali metal fluoride may be formed partially or wholly in situ by the self-condensation of an alkali metal salt of an activated fluorophenol F-Ar-QM or by the condensation of a substantially equimolar mixture of an activated difluorobenzenoid compound F-Ar-F and an alkali metal salt of a dihydric phenol The reaction may be carried out in a dipolar aprotic solvent under anhydrous conditions or in the melt. Aromatic sulphone copolymers may also be prepared by carrying out the reaction in the presence of a polyaryl sulphone containing repeat units -Ar<SP>1</SP>-SO 2 -, where Ar<SP>1</SP> is a bivalent aromatic residue, at least some of which have an aromatic ether or thioether group ortho- or parato the SO 2 - group. In the examples aromatic polymers are prepared by reacting (1) KF, 4 - (4 - fluorophenylsulphonyl)phenol, (2) KF, bis - (4 - chlorophenyl)sulphone, bis - (4- hydroxyphenyl)sulphone, (3) the anhydrous potassium salt of 4-(4-fluorophenylsulphonyl)- phenol and 4 - (4 - fluorophenylsulphonyl)- phenol, (4) KF, 2,2-bis-(4-hydroxyphenyl)-propane, bis - (4 - fluorophenyl)sulphone, (5) KF, 4,41 - bis - (4 - chlorophenylsulphonyl)- biphenyl, bis - (4 - hydroxyphenyl)sulphone, (6) KF, bis - (3,4 - dichlorophenyl)sulphone, bis - (4 - hydroxyphenyl)sulphone, (7) KF, 4,4<SP>1</SP> - bis - (4 - hydroxyphenylsulphonyl)- biphenyl, bis - [41 - (4 - chlorophenylsulphonyl)- biphenyl]sulphone, (8) KF, 4 - (4 - chlorophenylsulphonyl)thiophenol, (9) KF, 4 - (4- chlorophenylsulphonyl) - 4<SP>1</SP> - mercapto biphenyl.
