Poly(oxy‐2,6‐dimethyl‐1,4‐phenylene) (PPE) reacts with 1,2,4‐triazoline‐3,5‐diones to give poly([oxy‐2,6‐dimethyl‐3‐(1′, 2′,4′‐triazolidine‐3′,5′‐dione)‐1,4‐phenylene]‐co‐poly[oxy‐2,6‐dimethyl‐1,4‐phenylene]). Miscibility of these highly polar PPE copolymer with PS is probed for varying degree of polar substitution and various functional groups in the 4‐position of the heterocycle. The copolymers are miscible with polystyrene up to concentrations of counits of about 10%. For a selected blend system of PS and PPE modified with 4% of 4‐(4‐hydroxy‐3‐nitrophenyl)‐1,2,4‐triazoline‐3,5‐dione the concentration of PS was varied.
