Zusammenfassung:	- Ion exchangers (I) prepared by reacting a polyamine resin based on a cross-linked polyacrylamide matrix is reacted with acrylic acid (derivatives) or salts of an omega -haloalkanoic acid are new. Also claimed is a method of preparing propan-1,3-diol (II) by hydrating acrolein (III) to 3-hydroxy-propionaldehyde (IV) in the presence of (I) and by hydrogenation of (IV).
