ABSTRACT:
Amphoteric resins are prepared by the Strecker synthesis of crosslinked vinylcarbonyl polymers. The crosslinked vinylcarbonyl polymer such as, for example, polyacrolein is reacted with an amine component such as ammonia and an inorganic cyanide to obtain after hydrolysis resins having good weak base and weak acid exchange capacities. The amphoteric nature and higher capacities make them highly suitable for the removal of sulfur oxides from waste streams.
