Abstract

New Synthetic resins useful as inert material for separating layers in ion exchanger mixed bed filters. The new synthetic resins are copolymers of PA1 (a) substituted styrenes and/or methacrylates, PA1 (b) methacrylates of polyhydric alcohols and/or aromatic polyvinyl compounds and PA1 (c) unsaturated hydrocarbons which have at least two allyl groupings in the molecule, and/or polyvinyl ethers of polyhydric alcohols, and optionally PA1 (d) styrene.
