RESINAS PLASTICAS A BASE DE COPOLIMEROS RETICULADOS DE COMPOSTOS MONOVINILICOS E POLIVINILICOS PROCESSO PARA A SUA PREPARACAO E SEU EMPREGO COMO MATERIAL INERTER EM FILTROS DE LEITO MISTO DE TROCADORES DE IONS

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.
