Abstract

The complex formation between polycarboxybetaines (PCB) and polyanions can be enhanced and efficiently controlled by the proper choice of alkyl spacer between charges in the betaine moieties. Practical ramifications of the revealed role of the alkyl spacer in polyelectrolyte complexation as well as the pH-induced stabilization of the complexes that occurs under enzyme-friendly conditions might extend to areas of biotechnology, specifically in bioseperation and gene delivery.

2. Conformation of polyelectrolyte chains in dilute aqueous solutions investigated by conductometry. 4. Influence of molecular mass and charge density of the chains on conformation of symmetrical aliphatic ionene bromides

Abstract

The approach based on conductivity measurements, which provides valuable information on the conformation of polyions in salt-free dilute aqueous solutions that correlates well with data obtained by other methods is discussed. The results shows that both symmetrical and nonsymmetrical ionenes are valuable polycations to reveal the effect of mean charge density and the charge distribution of the chains on their properties.
