Synthesis and characterization of polyampholytic model networks: Effects of polymer composition and architecture
(2002)Synthesis and characterization of polyampholytic model networks were studied using group transfer polymerization (GTP). The degrees of swelling (DSs) of all the polyampholytic networks were also measured as a function of ...

Synthesis and characterization of polymer networks and star polymers containing a novel, hydrolyzable acetal-based dimethacrylate cross-linker
(2006)An acid-labile dimethacrylate acetal cross-linker, di(methacryloyloxy-1-ethoxy)methane (DMOEM), was synthesized by the reaction of 2-hydroxyethyl methacrylate and paraformaldehyde using p-toluenesulfonic acid and toluene ...

Synthesis and characterization of rigid functional anionic polyelectrolytes: Block copolymers and star homopolymers
(2012)Seven cyclolinear polymers bearing the tertiary-butyl α- (hydroxymethyl)acrylate (TBHMA) ether dimer were prepared using reversible addition-fragmentation chain transfer (RAFT) polymerization. Of the seven polymers, five ...

Synthesis and characterization of star polymers and cross-linked star polymer model networks containing a novel, silicon-based, hydrolyzable cross-linker
(2004)An acid-labile dimethacrylate cross-linker, dimethyldi(methacryloyloxy-1-ethoxy)silane (DMDMAES), was synthesized by the reaction of 2-hydroxyethyl methacrylate (HEMA) and dichlorodimethylsilane in the presence of ...

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 ...

Water-soluble ABC triblock copolymers based on vinyl ethers: Synthesis by living cationic polymerization and solution characterization
(1997)Water-soluble ABC triblock copolymers of methyl vinyl ether (MVE), ethyl vinyl ether (EVE), and methyl tri(ethylene glycol) vinyl ether (MTEGVE) of various block sequences and carrying 20 monomer units in each block were ...
