Abstract

The invention comprises p-linked polymers containing repeating units of the formula -Ar-C(F)(R)-O-, in which Ar is a p-phenylene group, which may be substituted by one or more perfluoroalkyl groups of 1-3 carbon atoms and/or by one or more nuclear fluorine atoms, and R is fluorine or a perfluoroalkyl group of 1-3 carbon atoms. The polymers are prepared by polymerizing alkali or alkaline-earth metal salts of phenols substituted in the nucleus with one or more perfluoroalkyl groups of 1-3 carbon atoms and optionally substituted in addition by one or more nuclear fluorine atoms (see Division C2), polymerization being effected by heating the salts with water. Examples are given in which the potassium salts of heptafluoro-p-cresol, nonafluoro-p-ethyl-phenol, nonafluoro - 2,4 - dimethylphenol are polymerized by heating in water to 70-100 DEG C. Some of the products yield elastomers when heated in vacuo to 180-250 DEG C. with an alkali or alkaline-earth metal salt.ALSO:The invention comprises alkali and alkaline-earth metal salts of phenols substituted in the nucleus with one or more perfluoroalkyl groups of 1-3 carbon atoms and optionally substituted in addition by one or more nuclear fluorine atoms. The salts may be prepared by the action of an alkali or alkaline-earth metal hydroxide, in the presence of a solvent, on a benzene hydrocarbon substituted with at least one nuclear fluorine atom and at least one perfluoroalkyl group of 1-3 carbon atoms. Examples are given of the manufacture of the potassium salts of heptafluoro-p-cresol, nonafluoro-p-ethyl-phenol nonafluoro - 3,4 - (or 2,5) - dimethylphenol and nonafluoro-2,4-dimethylphenol by the action of potassium hydroxide on octafluorotoluene, decafluoro-p-ethylbenzene, decafluoro-o-(or p-)xylene and decafluoro-m-xylene, respectively. The free phenols can be recovered by acidifying the salts. The salts are polymerizable (see Division C3).
