Synthesis and aqueous solution characterization of amphiphilic diblock copolymers containing carbazole
(2002)A series of near-monodisperse diblock copolymers of 2-(N-carbazolyl)ethyl methacrylate and 2-(dimethylamino)ethyl methacrylate (DMAEMA) of relatively low molecular weights (2600-24,000 g mol-1) were synthesized by group ...

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 aqueous solution characterization of novel diblock polyampholytes containing imidazole
(2002)A series of diblock copolymers of 2-(1-imidazolyl)ethyl methacrylate and tetrahydropyranyl methacrylate (THPMA) were synthesized by group transfer polymerization using propylene carbonate rather than tetrahydrofuran as the ...

Synthesis and characterization of electrolytic amphiphilic model networks based on cross-linked star polymers: Effect of star architecture
(2002)Amphiphilic model networks of a new structure, that of cross-linked "in-out" star copolymers, were synthesized by a one-pot preparation using group-transfer polymerization. The networks comprised hydrophobic methyl ...

The synthesis of 2-cyano-cyanothioformanilides from 2-(4-Chloro-5H-1,2,3- dithiazol-5-ylideneamino)benzonitriles using DBU
(2009)A series of 2-(4-chloro-5H-1,2,3-dithiazol-5-ylideneamino) benzonitriles were prepared from the reaction of 4,5-dichloro-1,2,3-dithiazolium chloride (Appel salt) and the corresponding anthranilonitriles. Reaction of the ...

Synthesis, characterization and evaluation of amphiphilic diblock copolymer emulsifiers based on methoxy hexa(ethylene glycol) methacrylate and benzyl methacrylate
(2004)Linear, amphiphilic diblock copolymers based on the nonionic, hydrophilic monomer methoxy hexa(ethylene glycol) methacrylate (HEGMA) and the hydrophobic monomer benzyl methacrylate (BzMA) of different molecular weights and ...

Synthesis, characterization and evaluation of amphiphilic star copolymeric emulsifiers based on methoxy hexa(ethylene glycol) methacrylate and benzyl methacrylate
(2005)Amphiphilic star copolymers were synthesized by sequential monomer and cross-linker additions using group transfer polymerization (GTP). Benzyl methacrylate (BzMA) and methoxy hexa(ethylene glycol) methacrylate (HEGMA) ...

Synthesis, characterization and modeling of ABC triblock terpolymers: The effect of block sequence
(2002)Four equimolar terpolymers comprising ten units from each of the monomers methoxy hexa(ethylene glycol) methacrylate (HEGMA), 2-(dimethylamino)ethyl methacrylate (DMAEMA) and methyl methacrylate (MMA) were prepared by group ...

Synthesis, characterization, and DNA adsorption studies of ampholytic model conetworks based on cross-linked star copolymers
(2008)Five model conetworks based on cross-linked star ampholytic copolymers were synthesized by group transfer polymerization. The ampholytic copolymers were based on two hydrophilic monomers: the positively ionizable ...
