A polyphenylene ether composition excellent in impact resistance, heat stability, gloss and processability which contains (a) 80-20 weight parts of polyphenylene ether resin, and (b) 20-80 weight parts of a rubber-reinforced polystyrene wherein 5-25 weight % of polybutadiene having 15-35% of 1,2-vinyl-structure is dispersed forming discontinuous elastomer phase, particularly said polyphenylene ether resin being a polymer having the following recurring unit I or units I and II: <IMAGE> wherein R1-R6 represent the same or different monovalent residual groups such as alkyl group having 1-4 carbon atoms excluding tert.-butyl group, aryl group, halogen or hydrogen, but R5 and R6 are not hydrogens at the same time. |
