| abstract | 885,719. Making porous ion-exchange resins. FARBENFABRIKEN BAYER A.G. March 6, 1958 [March 9, 1957], No. 7297/58. Class 87(2). [Also in Group IV(a)] Anion-exchange resins having a sponge structure are obtained by haloalkylating and then aminating the cross-linked polymer obtained by copolymerising an aromatic mono-vinyl compound with a polyethylinically unsaturated compound in the presence of at least 20% of an organic liquid which is a non-solvent for linear aromatic vinyl polymers but a solvent for the monomers. The porosity of the polymer depends on the proportion of organic liquid employed. In an example porous polymers were obtained from styrene, ethylstyrene, and divinylstyrene by emulsion polymerization using white spirit as pore forming liquid. This liquid was removed by drying from the resulting bead polymer which was then haloalkylated and aminated. In a further example a polymer was prepared from vinyl toluene and ethylene glycol dimetheacylic acid ester with n-decanol as the pore former.
