Abstract
A resin composition having nice color tone and high crack-resistance as well as flame-retardancy is obtained by blending PA0 (A) 100 weight parts of a resin composition containing a rubber-reinforced vinyl aromatic polymer and polyphenylene ether represented by the following general formula: ##STR1## wherein each of R.sub.1 and R.sub.2 represents a monovalent residue such as the same or different alkyl group having 1-4 carbon atoms, aryl group, halogen and hydrogen, and n represents the polymerization degree or a polyphenylene ether onto which a vinyl aromatic compound is graft-copolymerized, in which the polyphenylene ether content is 5-70 wt. % (based on the weight of the resin part), PA0 (B) 1-30 weight parts of a halogenated aromatic compound and PA0 (C) 0.5-20 weight parts of a non-crystalline ethylene-propylene copolymer.
