摘要:
A method of separating heteropoly compounds from mixtures of polyethers, polyesters and/or polyether esters, a protic component and heteropoly compounds, wherein the protic component is removed from the mixture and subsequently separating off the heteropoly compound as a separate phase. The polymer phase which remains is preferably brought into further contact with a solid adsorbent that is capable of adsorbing heteropoly compounds.
