Process for the chloromethylation of polymers for the production of anionic exchange resins |
| abstract |
Improved process for the chloromethylation of cross-linked vinylaromatic polymers and copolymers wherein a chlorine generator is incorporated into the reactants and a metallic chloride replaces part or all of the sulfuric acid used in forming the chloromethylating complex. The chloromethylated polymer may be further functionalized to produce an ion-exchange resin. |
