Aqueous size exclusion chromatography of random, diblock, and ABC triblock methacrylic polyampholytes
(1996)Aqueous size exclusion chromatography (SEC) at 1 M KCl and pH 8.5 was employed to probe the aggregation behavior of methacrylic polyampholytes. In agreement with earlier results obtained by light scattering techniques, ...

Cationic homopolymer model networks and star polymers: Synthesis by group transfer polymerization and characterization of the aqueous degree of swelling
(2000)A series of hydrophilic model networks based on homopolymers of a weak base were prepared using group transfer polymerization (GTP) and characterized in terms of their aqueous degree of swelling as a function of pH. This ...

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 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 ...

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 ...
