Abstract: The solubility properties of polv(2,6-dimethyl-1,4-phenylene oxide)(PPO), carboxylated PPO(C-PPO), bonzcylated PPO(BA-PPO), benzensulfonylated PPO(BS-PPO)and sulfonated PPO(S-PPO)in various solvents were studied. The effect of the polarity of mo-dified PPO's on the solubility parameters determined by the intrinsic viscosity method were discussed.

Key words: poly(2,6-dimethyl-1,4-phenylene oxide)(PPO), carboxylated PPO, benzoylated PPO, benzenesulfonylated PPO, sulfonated PPO, intrinsic viscosity, solubility, parameter
