Abstract
The paper presents some physico-chemical characteristics of dilute sol utions of exopolysaccharide pullulan and its carboxymethyl, sulfoethyl and sulfopropyl ionic derivatives. On-line size exclusion chromatogra phy/multi-angle laser light scattering (SEC/MALLS) was used for establ ishing their weight average molecular weight (M(w)), number average mo lecular weight (M(n)), polydispersity index (I-p = M(w)/M(n)) and radi us of gyration R(g).
