A phenylene sulfide/sulfone polymer with relatively good melt stability and a method of producing such a polymer are provided. A previously produced phenylene sulfide/sulfone polymer is redissolved in N-methyl-2-pyrrolidone to form a solution. This solution is combined with an alcohol to precipitate highly melt stable phenylene sulfide/sulfone polymer in a particulate form. The alcohol has one to four carbon atoms, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and the like and mixtures thereof.

A process is disclosed which comprises reacting hydrogen sulfide with azolesulfonates and sulfinates to give 2-mercaptoazoles. One embodiment of the invention describes removal of oxidized forms of 2-mercaptobenzothiazole including benzothiazole-2-sulfonates from effluent by treatment with hydrogen sulfide.
