Abstract

The invention relates to thermoplastic compositions comprising mixtures of PA0 (A) 100 parts by wt. polyphenylene ethers; PA0 (B) 2-40 parts by wt. polyoctenylene; and PA0 (C) the following additives in amounts given as wt. % of the overall molding or forming composition: PA1 up to 50 wt. % reinforcing and filling materials; PA1 up to 60 wt. % condensation polymers; PA1 up to 15 wt. % flame retardants; and PA1 up to 5 wt. % other additives. The invention further relates to methods for producing such mixtures in the molten state and in solution.
