ABSTRACT:
A method is disclosed to prepare a polymeric material by filtering solutions of poly(arylene ether) and/or poly(alkenyl aromatic) through one or more filtration systems to provide a material having reduced levels of particulate impurities. The polymeric material prepared is suitable for use in data storage media applications.
