6-dimethylphenylene oxide) (PPO) is an important engineering plastics and is synthesized by oxidative polymerization of 2
6-dimethylphenol (DMP) in an organic solvent
therefore both a solvent recovery process and an explosion-proof reactor are needed.On the view of green chemistry
the use of water as the reaction medium is environmentally friendly.Furthermore
PPO can be separated from water easily due to its insolubility in water.The synthesis of PPO by oxidative polymerization of DMP in oi/l water biphase and aqueous media has been developed.The polymerization of2
6-dimethylphenol
including the oxidative coupling mechanism
and factors that influence the polymerization rate of DMP
oxidative coupling selectivity and molecular weight of PPO in oi/l water biphase and aqueous media
