A method for forming a polyarylene sulfide with a relatively low content of volatile malodorous compounds is provided. More particularly, such low compound levels may be achieved by subjecting a washed polyarylene sulfide to a heat treatment in the presence of an atmosphere that includes an inert gas, wherein the heat treatment occurs at a temperature of from about 150° C. to about 275° C.
