## Abstract Polyphenylene oxide (PPO) was prepared via oxidative coupling polymerization of 2,6βdimethylphenol (DMP) catalyzed by copper salt. The ligand was a novel series of random copolymers (PSVP) of styrene and 4βvinylpyridine prepared by reversible additionβfragmentation chain transfer (RAFT)
The ligands bipyridine (bpy), 4,4 -dimethoxy-2,2 -bipyridyl (dMeObpy), 4,4 -dimethyl-2,2 -bipyridyl (dMebpy), 4,4dichloro-2,2 -bipyridyl (dClbpy) and 4,4 -dinitro-2,2 -bipyridyl (dNO 2 bpy), when combined with copper(II) nitrate render active catalysts. The highest activity was found for bpy as the
