Abstract: The invention relates to a process for using nitric acid to oxidize polyarylene sulfide to polyarylene sulfoxide, oxidizing at least 98% of the sulfide groups of the polyarylene sulfide to sulfoxide groups. According to the invention polyarylene sulfide is treated with nitric acid at a concentration of from 60 to 80% with heating. The polyarylene sulfoxide prepared by the novel process can be used as an excellent chemical blowing agent for foaming thermoplastics.

Abstract: Polyaryiene sulfone fiber material, especially web, is obtained by oxidizing polyarylene sulfide fiber material with a peracid/acid mixture of an organic acid at 60 to 100° C. for 10 seconds to 45 minutes. Since this process provides a substantative degree of oxidation within a very short reaction time, one advantage of the process is that the rapidity of the oxidation renders continuous processes for oxidizing polyarylene sulfide fibers economical.
