2,5-diaminobenzene-1,4-dithiol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Next, the 2,5-diamino-1,4-benzenedithiol vapor in the condensing chamber 2 was adiabatically expanded, and the introduced modified particles (35) were exposed thereto for 18 minutes. Consequently, a further polymerization reaction between 1,4-butanedisulfonyl chloride and 2,5-diamino-1,4-benzenedithiol took place on the surface of the modified particles (35), forming a film of 1,4-butanedisulfonylchloride-2,5-diamino-1,4-benzenedithiol co-polymer.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Next, the 1,4-butanedisulfonyl chloride vapor in the condensing chamber 2 was adiabatically expanded, and the introduced base particles were exposed thereto for 8 minutes. Consequently, a polymerization reaction between 2,5-diamino-1,4-benzenedithiol and 1,4-butanedisulfonyl chloride took place on the surface of the base particles, forming a film of 2,5-diamino-1,4-benzenedithiol-1,4-butanedisulfonyl chloride co-polymer.

Conditions: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2,5-Diamino-1,4-benzene dithiol dihydrochloride (1.5544 g, 6.3 mmol), 2-benzoxazole terephthalic acid (1.7956 g, 6.3 mmol) and 10.2 g of polyphosphoric acid (83% P2O5) were placed in a resin flask equipped with a mechanical stirrer, nitrogen inlet/outlet tubes, a vacuum connector and a side opening on the resin flask. With nitrogen continuously flowing, the solution was heated slowly to 60° C. for 24 hours and 90° C. for 16 hours to remove the hydrochloride. The mixture was heated at 160° C. for 17 hours, then at 190° C. for 17 hours. Work-up, as in the preceeding Example, gave a polymer with [N]=0.96 dl/g, methanesulfonic acid at 30° C. equipped with a mechanical stirrer, nitrogen inlet/outlet tubes to remove the hydrochloride The mixture was heated at 160° C. for 17 hours at 30° C.
