The compatibility of poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) with random copolymers of ortho ‐ and para ‐fluorostyrene as well as with ortho ‐ and para ‐chlorostyrene of various copolymer compositions was examined. The compatibility was studied by DSC and visual observation of film clarity. It was found that copolymers of ortho ‐fluorostyrene with para ‐chlorostyrene containing 15–74 mol % p ‐CIS are compatible with PPO in all proportions. Compatibility of the PPO/poly‐( ortho ‐fluorostyrene‐co‐ ortho ‐chlorostyrene) system was observed for copolymers containing between 15 and 36 mol % ortho ‐chlorostyrene. Copolymers of para ‐fluorostyrene with para ‐chlorostyrene, as well as copolymers of para ‐fluorostyrene with ortho ‐chlorostyrene appear to be incompatible with PPO at 210°C.
