Abstract

We have discovered that organic solutions or dispersions of monomers, pre-polymers, and polymers, can be reliably purified to the levels required by the electronics industry using a combination of microfiltration and ion exchange. The combination of both separation techniques is necessary in order to ensure removal of a broad spectrum of elemental impurities.
