Abstract (en)
[origin: WO2011043803A1] Methods of reducing impurities from a solid epoxy resin in a discrete particulate form. The methods include heating a heterogeneous mixture of the solid epoxy resin, while maintaining the solid epoxy resin in discrete particulate form, and a solution to a predetermined temperature below the solid epoxy resin's softening point temperature. Agitating the heterogeneous mixture at the predetermined temperature for a predetermined time to extract ionic species from the solid epoxy resin into the solution and separating the solid epoxy resin in discrete particulate form from the ionic species in solution. The separated solid epoxy resin having a reduced impurity content relative to the heterogeneous mixture prior to heating.
