摘要：
Poly(arylene sulfide/sulfone) polymers are treated in order to increase melt stability and decrease impurities by contacting the poly(arylene sulfide/sulfone) polymer with a soluble zinc compound and an acidic solution. In one embodiment, the polymer is treated first with the soluble zinc compound, followed by treatment with the acidic solution. In another embodiment, the polymer is treated in one step with a solution comprising a water soluble zinc compound in an acidic solution.
