Abstract

The invention relates to thermoplastic compositions made up of: PA0 A. Polyphenylene ethers, in an amount of 15-95 wt. parts; PA0 B. Styrene resins, in an amount of 0 to 70 wt. parts; PA0 C. E-SBR rubbers, in an amount of 3-15 wt. parts; PA0 D. Styrene-butadiene polymers prepared by emulsion polymerization (with styrene incorporated in the copolymer in the amount of 3-15 wt. parts; and PA0 E. Optionally, other additives. The invention further relates to a method for preparing such thermoplastic compositions.
