Abstract

Disclosed herein are melt-stable thermoplastic resin compositions comprising (A) 100 parts by weight of a particular poly(arylene thioether) block copolymer, (B) --400 parts by weight of at least one of thermoplastic resins, and (C) 0-400 parts by weight of at least one filler per 100 parts by weight of the resin components. At least either one of Component (B) and Component (C) is contained in a proportion of at least 0.1 part by weight per 100 parts by weight of Component (A). The poly(arylene thioether) block copolymer alternately comprise 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## Also disclosed are compositions obtained by stabilizing by the melt-stable thermoplastic resin compositions with a basic compound and products molded or formed product from these compositions.
