Abstract
Abstract A resin composition consisting essentially of (A) a polyphenylene ether having added thereto an unsaturated carboxylic acid having 3 to 10 carbon atoms or an anhydride thereof (component A), (B) a polyphenylene sulfide (component B), and (C) a polyisocyanate compound (component C), the weight ratio of component A to component B being from 5:95 to 95:5 and the amount of component C being from 0.01 to 10% by weight based on the total weight of components A and B; and molded articles therefrom.
