The subject of the study was investigation of influence of substituent type on the properties of starch derivates in diluted solutions. Three samples were prepared: two anionic (carboxymethyl starch, CMS) and one cationic starch (KS). Starch derivate

Three samples of corn starch and three samples of potato starch were transformed to carboxymethyl starch (CMS) using a two-step etherification with sodium monochloroacetate in ethanol as the reaction medium. The degree of substitution (DS) of the syn

Carboxymethyl starch samples were prepared by etherification in heterogeneous media. Three samples were prepared from corn starch and three samples from potato starch. Degree of substitution of prepared samples ranged from 0.40 to 1.10. The samples w

Crosslinked carboxymethyl starch (CMS) was synthesized from potato starch in a single-step procedure with mono- (MCA) and dichloroacetic acid (DCA), using the well-known Williamson reaction. The products varied in their degree of substitution DS (ave

Dynamic light scattering measurements were performed on aqueous alcoholic salt solutions of poly(diallyl-N,N-dimethylammonium chloride) (PDADMAC, Mw=2.5×105 g mol−1) in the semidilute regime, where the salts used were NaCl and Na2SO4. The results

The synthesis of the bi-furcated complementary oligonucleotides 2 and 3 is described and their complex formation is studied as a function of their molar ratio and ionic strength by means of temperature-dependent UV- and CD spectroscopy as well as by
