Anionic Vinyl Polymerization
The concept of anionic polymerization was first developed by Ziegler and Schlenk in early 1910. Their pioneering work on the polymerization of diene initiated with sodium metal set the stage for the use of alkali metal containing aromatic hydrocarbon complexes as initiators for various α-olefins. In 1939, Scott and coworkers used for the first time the alkali metal complexes of aromatic hydroca...
متن کاملAnionic regions in nuclear proteins
Recent technological advances have generated a flood of protein sequence data, much of it deduced from the DNA sequences of cloned genes. In this commentary I will discuss an unexpected sequence motif found in a number of proteins that are thought to interact directly or indirectly with DNA. The motif, which I will term an Aregion (acidic region), is a local high concentration of acidic residue...
متن کاملBound anionic states of adenine.
Anionic states of nucleic acid bases are involved in DNA damage by low-energy electrons and in charge transfer through DNA. Previous gas phase studies of free, unsolvated nucleic acid base parent anions probed only dipole-bound states, which are not present in condensed phase environments, but did not observe valence anionic states, which for purine bases are thought to be adiabatically unbound...
متن کاملPolymerization of anionic wormlike micelles.
Polymerizable anionic wormlike micelles are obtained upon mixing the hydrotropic salt p-toluidine hydrochloride (PTHC) with the reactive anionic surfactant sodium 4-(8-methacryloyloxyoctyl)oxybenzene sulfonate (MOBS). Polymerization captures the cross-sectional radius of the micelles (approximately 2 nm), induces micellar growth, and leads to the formation of a stable single-phase dispersion of...
متن کاملHemolytic Systems Containing Anionic Detergents
1. The members of the homologous series of anionic detergents, the sodium salts of the sulfated straight chain alcohols with the general formula C(n)H(2n+1).SO(3).Na, are hemolytic, the lytic activity being at a maximum when the compound contains 14 carbon atoms in the chain. In systems in which lysis is comparatively rapid, the hemolytic effect increases with increasing pH, but in systems cont...
