ABSTRACT:
Disclosed herein are (1) a composition which is prepared by combining 0.2 to 90 parts by weight of a cross-linked polyarylene thioether having a melt viscosity of 5.times.10.sup.5 to 1.times.10.sup.9 poise, which becomes gel under melting, with 100 parts by weight of a resin consisting of polyarylene thioether, which has a repeating unit of ##STR1## as the main constituent, having a melt viscosity of 10 to 5.times.10.sup.4 poise and (2) a composition of polyarylene thioether for molding, which is prepared by combining not more than 400 parts by weight of a fibrous filler and/or an inorganic filler with 100 parts by weight of the above-mentioned composition (1), is excellent in an antiflash property, is high in a mechanical strength and a thermal stability and is easily processed on melt molding and can easily recycle its molded scraps.
