ABSTRACT:
The properties of arylene sulfide polymers are improved by treating the polymer with a fluid treating agent selected from the group consisting of hydrogen peroxide, an alkali metal or alkaline earth metal hypochlorite, sulfuric acid, chlorine, sulfuryl chloride, nitrogen dioxide, chromium trioxide, alkali metal permanganates and nitric acid under conditions of concentration of treating agent, time and temperature to effect the desired improvement.
