SYNTHETIC RESINS BASED ON CROSSLINKED COPOLYMERS OF MONO- AND POLYVINYL COMPOUNDS, PROCESS FOR THEIR PREPARATION AND THEIR USE AS INERT MATERIAL IN ION EXCHANGE MIXED-BED FILTERS

摘要

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