Obtaining Ion-Exchange Materials and Studying their Properties

Özet

It has been realized modification of phenol-formaldehyde oligomers by acetamide and oksamide. It has been studied ways of obtaining sulphocationites on the basis of phenolformaldehyde oligomers modified by asetamide and oksamide. To the comparative effect the changing of unmodified phenol-formaldehyde oligomer has been researched. At the end of modification reaction into each benzyl ring there was fed sulfonate group. Main indices of modified oligomers and sulphocationites have been researched. It has been revealed that as a result of including additional functional groups into modified oligomers basic characteristics of sulphocationites have been improved.
