Chemistry of 4-dicyanomethylene-1,2,6-thiadiazines
(2000)The chlorine atoms in 3,5-dichloro-4-dicyanomethylene-1,2,6-thiadiazine 1 are readily displaced by thiophenols in the presence of Hünig's base, the first at -78 °C and the second at 20 °C to give the orange mono- and ...

Near-monodisperse α-hydroxy and α,ω-dihydroxy amine-based polymers: Synthesis and characterization
(1999)α-Hydroxy and α,ω-dihydroxy polymers of 2-(dimethylamino)ethyl methacrylate (DMAEMA) of various molecular weights were synthesized by group transfer polymerization (GTP) in tetrahydrofuran (THF), using 1-methoxy-1-(trime ...

Redox chemistry of sulphate and uranium in a phosphogypsum tailings dump
(2010)The present study aims to assess the effect of redox conditions existing within the tailings dump on the stability of phosphogypsum (e.g. sulphate reduction) and uranium(VI). Phosphogypsum sampling and in-situ measurements ...

Serum soluble interleukin-2 receptors in epithelial ovarian cancer patients
(1995)The levels of soluble interleulkin-2 receptors (sIL-R2) were measured in the serum of 52 patients with epithelial ovarian carcinoma as well as in 25 age and sex-matched normal controls. The mean serum level of sIL-2R was ...

Synthesis and aqueous solution characterization of catalytically active homopolymers, block copolymers and networks containing imidazole
(2000)Imidazole-containing polymers were prepared and characterized in terms of their hydrolytic activity. Unlike similar materials synthesized in the 1960s, the polymers are of precise molecular weight and controlled structure ...

Synthesis and characterization of amphiphilic multiblock copolymers: Effect of the number of blocks on micellization
(2009)Five linear amphiphilic multiblock copolymers based on 2-(dimethylamino) ethyl methacrylate ("D") and methyl methacrylate ("M"), bearing from two to six blocks, were synthesized using sequential group transfer polymerization. ...
