A cation exchange resin prepared from itaconic acid may be expected to have a large ion exchange capacity. The resins obtained by Akashi3) and Sugihara4), however, showed relatively low ion exchange capacities. The resins prepared by the solution copolymerization of itaconic acid and divinylbenzene in methyl alcohol, ethyl alcohol and acetone showed exchange capacities of 4.3-7.6, 7.86 and 9.57 meq./g. respectively. The resin obtained by ...
