摘要：

By aminolysis of poly(acrylonitrile) with dicyandiamide and a subsequent reaction with hydroxylamine, polyampholytes are formed, which exhibit different ranges of insolubility around the isoelectric point. The reason for the improved solubility of the twice modified polymer is its higher concentration of dissociable functional groups. The aggregation behaviour of the polyampholyte is discussed on base of the intrinsic viscosities measured in dependence on the pH value. © 1990 Akademie Verlag GmbH, Berlin
