Abstract: In the paper the miscibility of carboxylated poly(phenylene oxide)(CPPO)/poly(styrene-co-4-vinylpyridine)(PSVP)blends was investigated by DSC and DMA. It was found that the CPPO/PSVP blends possessed relatively good miscibility compared with CPPO/PS, and this was attributed to the ion ion interactions resulted from the proton transfer between the carboxylic groups of CPPO and the pyridine groups of PSVP.

Key words: carboxylated poly(phenylene oxide), poly(styrene-vinylpyridine), miscibility
