Abstract (en)
[origin: WO2009062923A2] The invention relates to a method for producing polyaryl ethers. The invention is characterized by a polycondensation of the monomer units as the starting materials and a concurrent irradiation with microwaves. The invention allows the production of thermoplastic molding masses having improved color properties.
