Abstract
A series of water-soluble polymers was synthesized by polycondensation of cyclodextrin with epichlorohydrin under basic conditions. We studi ed their molecular distribution as a function of molar ratios of react ants. NaOH concentration showed that very high molecular averages (Mw > 10(6)) can be obtained. The substitution patterns were determined by C-13 NMR analysis and standard methylation analysis of polysaccharide s. The formation of side chains and bridges consisting of sequences of poly(2-hydroxypropyl)ether units were demonstrated by electrospray io nization mass spectrometry and gas liquid chromatography-mass spectrom etry. The predominant position of substitution depends on the NaOH con centration.
