ABSTRACT:
A novel process is disclosed for the polymerization of phenols, e.g., xylenols, and recovery of polyphenylene ethers from the polymerization mixture. The method is based on the use of hot methylene chloride as a reaction solvent, elevated oxygen pressure and separation of the polyphenylene ether as a solid complex with methylene chloride upon cooling. Also a feature is the recycle and recovery of methylene chloride.
