ABSTRACT:
Disclosed herein are poly(arylene thioether) block copolymer fibers formed by melt-spinning a thermoplastic material composed of (A) 100 parts by weight of a particular poly(arylene thioether) block copolymer, (B) up to 50 parts by weight of at least one other thermoplastic resin and (C) up to 10 parts by weight of at least one filler. The poly(arylene thioether) block copolymer alternately comprises at least one poly(arylene thioether-ketone) block having predominant recurring units of the formula ##STR1## wherein the --CO-- and --S-- are in the para position to each other and at least one poly(arylene thioether) block having predominant recurring units of the formula ##STR2##
