Latest Patents

Mukai holds a patent for a process for the production of phenylene ether oligomer. This process involves the oxidative polymerization of a specific bivalent phenol compound and a specific monovalent phenol compound in an aromatic hydrocarbon solvent. After the polymerization is terminated, the aromatic hydrocarbon solvent is replaced with a water-soluble organic solvent that has a higher boiling point. The resultant phenylene ether oligomer solution is then brought into contact with water, which precipitates the phenylene ether oligomer as particles. This innovative method enhances the efficiency and quality of phenylene ether oligomer production.
