Synthetic resins based on crosslinked copolymers of monovinyl and
polyvinyl compounds
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.
