摘要：

Oxidative copolymerization of phenol while continuously adding a small amount of 4-phenylphenol as an endcap was performed by using an enzyme model catalyst, followed by reprecipitation. Consequently, multi-branched poly(phenylene oxide)s were obtained with number-averaged molecular weights of 18,000-28,000, showing both high thermal stability beyond 470 degrees C and low dielectric constant of 2.43 @ 10 GHz.
