The structure of the O-antigen polysaccharide from Escherichia coli strain F171 has been determined. NMR analysis of the polysaccharide showed that it was composed of pentasaccharide repeating units. The 1H and 13C signals were assigned by 2D NMR tec

Four EBE copolymers (E = oxyethylene repeat unit, B = oxybutylene repeat unit) based on a B20 central block and end blocks ranging from 58 to 260 E units were studied. Rheological measurements (oscillatory and steady shear) were used to confirm gel b

This paper describes changes in the cationic polyelectrolyte PCMA coil conformation when the anionic surfactant SDS is added in the presence of a simple salt. Four different SDS/PCMA mass concentration ratios (0.074, 0.149, 0.223, and 0.298, correspo

Light scattering measurements (dynamic and total intensity) have been made on the complex formed between the polyelectrolyte sodium poly(styrene sulfonate) (NaPSS) and the ionic surfactant cetyltrimethylammonium bromide (CTAB). The influence on the c
