Improved thermoplastic compositions comprising a polyphenylene ether and an aromatic polyalkenyl resin. In these compositions, a diblock copolymer comprising from 45 to 60% of polystyrene and from 55 to 40% of hydrogenated polybutadiene by weight is used at least as a part of the aromatic polyalkenyl resin. This block copolymer appreciably improves the physical properties, more particularly the impact resistance, of the compositions. |
