  • Process for the removal of alkali from condensation resins
    Patent number: 5770677
    Abstract: A process for the preparation of a condensation resin of low catalyst content from a ketone and an aldehyde comprising reacting the ketone and aldehyde in a polycondensation reaction in an aqueous medium in the presence of a basic catalyst to form the resin, which is contaminated with alkali ions from the basic catalyst, and then exposing the resin to an electrical field in a cell demarcated by ion-selective membranes permeable to the alkali ions whereby alkali ions are caused to migrate out of the resin through the membranes. Also, a process for the removal of alkali from condensation resins as described above.
