ABSTRACT:
Polyphenylene sulfone fibers mainly consisting of a structural unit represented by a general formula ##STR1## (x is 0 or 1 or 2) wherein x, the average value of x, is 1.0 to 2.0, and a method for production thereof. These fibers are prepared by modifying polyphenylene sulfide fibers, whose specific surface area and degree of orientation are more than 0.4 m.sup.2 /g and more than 70%, respectively, to polyphenylene sulfone fibers represented by a main constituting unit with organic peroxides. These fibers have excellent heat and chemical resistance.
