Polyphenylene oxide properties
WebPolyphenylene Ether (PPE) - A thermoplastic, linear, noncrystalline polyether obtained by the oxidative polycondensation of 2,6-dimethylphenol in the presence of a copper-amine-complex catalyst. Polyphenylene ether, also called polyphenylene oxide, is usually blended with polystyrene to improve its toughness and processability. Polyphenylene ether has … WebPolystyrene (PS) and Polyphenylene oxide (PPO) constitute one of the important and explored polymer blend system. PPO is known as a good engineering polymer with superior mechanical properties and good miscibility with PS [2, 3]. A combination of polymers is increasingly found to meet the specific property requirements of new end uses.
