Poly trimethylammonium

Cationic poly(vinyl alcohol) has been prepared by the reaction of A/-(3-chloro-2-hydroxypropyl)-Ai,Ai,A/-trimethylammonium chloride, PVA, and sodium hydroxide (143). Reactions between alkyUdene epoxide and PVA in particulate, free-flowing form in an alkaline environment have been reported (144). [Pg.481]

Small fractions of a similar type of merocyanine dye moieties (Me) were also covalently tagged onto poly(sodium 2-acrylamido-2-methylpropanesulfonate) (AMc-3, 4) and poly[(3-(methacrylamino)propyl)trimethylammonium chloride] (QMc-1, 5) [49], The observed pKobs value of 10.92 for AMc-3 was higher than that for the neutral reference (NMc-3, 6) by 2.24 pH units. By contrast, the... [Pg.61]

Currently available BAS include cholestyramine, colestipol and colesevelam hydrochloride (colestimide). Cholestyramine comprises a long-chain polymer of styrene with divinylbenzene trimethylbenzylammonium groups, whereas colestipol is a long-chain polymer of l-chloro-2,3-epoxypropane with diethylenetriamine. Colesevelam HCl is poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and 6-bromo-hexyl-trimethylammonium bromide. Bile-acid binding is enhanced and stabilised in the latter compound by long hydrophobic sidechains, increased density of primary amines, and quaternary amine sidechains. For this reason, colesevelam HCl exhibits increased affinity, specificity and capacity to bind bile acids compared with the other BAS. Colesevelam HCl also binds dihydroxy and trihydroxy bile acids with equal affinity, contrasting with cholestyramine and colestipol that preferentially bind dihydroxy bile acids (CDCA and deoxycholic acid). The latter BAS can lead to an imbalance towards trihydroxy bile acids and a more hydrophilic bile-acid pool. [Pg.134]

As a result, zones A, B, and C have comparatively a basic, neutral, and acidic character, respectively. Increasing the DC electric current leads to the overall acidification of the gel sample (see Fig. 6, curve 4) due to the easy ionization of the acidic groups. Consequently, this narrows the zones B and C and expands zone A. Polybetaine hydrogel membranes of isopropyl-2-[2 -(trimethylammonium)ethyl phosphoryl] ethyl fumaramate and 2-hydroxyethyl methacrylate effectively enhance the water content in comparison with poly(2-hydroxyethyl methacrylate) [224]. The content of water in hydrogel membranes increases, but the amount of adsorbed BSA decreases with the increase of the betaine content in the feed. The values of the tensile strength and tensile elongation of the hydrogel reach 68.4 g mm and 239%, respectively. [Pg.196]

None of the poly-amino acids were found to be very soluble in any of the above mixtures. DGK3M was observed to be partially, but incompletely soluble in the SDS, dodecyl trimethylammonium, and octyl glucoside mixtures. The general difficulty of solubilizing these polypeptides in traditional denaturant and detergent solutions may reflect the inability of the solutions to overcome a kinetic barrier to disaggregation and should not necessarily be taken to imply thermodynamic instability of the fiiUy dispersed proteins in the solutions. [Pg.304]

A similar photo-effect on the swelling of cross-linked poly(methacrylic acid) (PMA) was observed in the presence of 4-phenylazophenyl trimethylammonium ions (J9) [38]. An increased cis content of the chromophore by photoirradiation at a pH in the range of conformation unfolding of PMA led to an increased ionization and thus enhanced swelling. The conversion efficiency of light energy to mechanical work was calculated to be 3 x 10 . ... [Pg.46]
