Abstract

1426207 Ion-exchange BADISCHE ANILIN- & SODA-FABRIK AG 24 May 1973 [25 May 1972] 24805/73 Heading B1J [Also in Division C3] Ion-exchanging porous shaped articles, e.g. filaments, fibres, woven fabrics or membranes, are made by adding a mono-vinylaromatic compound (which may be substituted in the vinyl group) and an aromatic divinyl compound to a homogenous mixture of an olefine polymer in a solvent of low volatility (as defined), the monomers in the mixture are polymerised, the mixture is converted to a shaped article, the solvent is removed e.g. by washing with a volatile solvent which is a non-solvent for the polymers, and ion exchange groups are introduced into the article. In examples the ionexchangers were used to decopper an aqueous copper tetramine sulphate solution containing copper, reduce the hardness of water and to demineralise water.
