摘要

Novel water-soluble cationic starch esters, namely starch-4-(N, N, N-trimethylammonium) butyrate chloride with high degree of substitution (DS) of up to 0.7 could be easily prepared by conversion of starch of different molar mass with the imidazolide of 3-carboxypropyl-trimethylammonium chloride (CPTMACl) homogeneously in dimethyl sulfoxide (DMSO). The products were characterized in detail by FTIR and NMR spectroscopy, including two-dimensional methods. The cationic starch esters possess a high antibacterial activity.
