    摘要: A process for efficiently manufacturing high purity polyarylene sulfide. The process comprises feeding a liquid or gaseous sulfur compound (e.g. hydrogen sulfide) to a mixture comprising lithium hydroxide and a non-lithium hydroxide solid compound (e.g. alkali metal chloride or alkaline earth metal chloride) in a non-protonic organic solvent (e.g. N-methyl-2-pyrrolidone), separating the alkali metal chloride or alkaline earth metal chloride, adjusting the sulfur content of the reaction mixture, feeding a dihalogeno aromatic compound e.g. p-dichlorobenzene) to effect a polycondensation reaction, and adding of an alkali metal hydroxide (e.g. sodium hydroxide) to recover lithium ion.

    摘要: A process for preparing a polyarylene thioether, comprising oxidation polymerizing at least one compound selected from the group consisting of diaryl disulfides represented by the formula (I): ##STR1## wherein, S is a sulfur atom, R.sup.1 to R.sup.8 are identical or different and each is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, a halogen atom or an alkoxyl group having 1 to 10 carbon atoms, with at least one catalyst selected from the group consisting of vanadyl acetylacetonato, vanadyltetraphenyl porphyrin, vanadium acetylacetonato, vanadyl porphyrin, vanadium porphyrin, oxymolybdenum acetylacetonato and oxytungsten acetylacetonato, in the presence of an acid. Reaction conditions of the process are very mild, and the process is relatively simple and easy. In addition, the process is commercially advantageous in that very inexpensive reactants and catalysts can be used.

    摘要: Novel processes are provided for synthesizing 2,2-bis(4-fluorophenyl)hexafluoropropane and the use of this synthesized monomer in polymerization reactions to form poly(arylethers) and poly(arylthioethers). Synthesis of 2,2-bis(4-fluorophenyl)hexafluoropropane involves converting the commonly available compound Bisphenol AF to an amino-substituted form, followed by treatment with borofluoric acid and a nitrite, and then an aromatic solvent to obtain the monomer. The monomer can be mixed with either a dihydroxy diphenyl hexafluoropropane or a dimercapto diphenyl hexafluorpropane to cause a nucleophilic substitution reaction, thereby yielding the desired poly(arylether) or poly(arylthioether).
