Claims
- 1. A process for producing an aromatic sulfide polymer, comprising the step of
- reacting one gram-equivalent of elementary sulfur, 0.7 to 1.3 gram-equivalents of a polyhalogen-substituted aromatic compound, 0.6 to 1.4 gram-equivalents of an aldehyde or a condensate thereof and 1.2 to 2.5 gram-equivalents of a caustic alkali in 0.02 to 5 liters of an organic solvent at a temperature of 100.degree. to 300.degree. C.
- 2. A process according to claim 1, wherein one gram-equivalent of elementary sulfur, 0.8 to 1.2 gram-equivalents of said polyhalogen-substituted aromatic compound, 1.4 to 1.7 gram-equivalents of said caustic alkali are reacted in 0.02 to 5 liters of said organic solvent at a temperature of 150.degree. to 280.degree. C.
- 3. A process according to claim 1 or 2, wherein said elementary sulfur is rhombic sulfur, monoclinic sulfur or amorphous sulfur.
- 4. A process according to claim 1, wherein said polyhalogen-substituted aromatic compound is a member selected from the group consisting of dichlorobenzenes, dibromobenzenes, trichlorobenzenes, 1-methoxy-2,5-dichlorobenzene, 2,5-dichlorotoluene, 1,4-dichloronaphthalene, 4,4'-dichlorobiphenyl, 4,4'-dichlorodiphenyl ether, 3,5-dichlorobenzoic acid, 3,3'-dichlorodiphenyl sulfone, 3,3'-dichlorodiphenyl sulfoxide and 3,3'-dichlorodiphenyl sulfide.
- 5. A process according to claim 1, wherein said aldehyde or said condensate thereof is a member selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde, paraformaldehyde, trioxane, polyoxymethylenes, paraacetaldehyde and metaacetaldehyde.
- 6. A process according to claim 1, wherein said organic solvent is a member selected from the group consisting of hexamethyl phosphoric triamide, N-methylpyrrolidone, tetramethyl-urea, dimethylacetamide and tetramethylene sulfoxide.
