| Popis: |
A series of water-soluble polymers were prepared by reacting α- and β-cyclodextrin with epichlorohydrin in NaOH solutions. Depending on the experimental conditions, polymers having very high molecular weight averages (Mw > 106 g.mol−1) can be obtained. However, low Mw fractions (Mw < 10000) were always present. The substitution patterns were determined by 13C NMR analysis and standard methylation analysis of polysaccharides. The formation of side chains and bridges consisting of sequences of poly(2-hydroxypropyl)ether units were demonstrated by electrospray ionization mass spectrometry and gas liquid chromatography — mass spectrometry. The predominant position of substitution depends on the NaOH concentration. |
