Synthesis and characterization of well-defined methacrylic-based block ionomers
… the incorporation of t-butyl methacrylate into block copolymers utilizing anionic living polymerization techniques. The synthesis of t-butyl methacrylate/n-hexyl methacrylate and t-butyl methacrylate/2-ethylhexyl methacrylate di- and triblock copolymers was done by initiation with …

Structural and morphological characterization of model elastomeric ion containing polymers
… particular interest are those materials termed ionomers which contain ionic groups that are typically less than 15 mole percent. These ionic interactions provides an additional means of controlling polymer structure and properties. In the conventional ionomers, the ionic groups are placed …

Ionic Copolymer-Magnetite Complexes for Magnetic Resonance Imaging and Drug Delivery
… phosphonate and carboxylate-containing graft and block copolymers. Oleic-acid coated magnetite nanoparticles (8-nm and 16-nm diameters) were investigated. Cisplatin and carboplatin were used as sample drugs. The potentials of the magnetite-ionomer complexes as dual drug delivery carriers and …

Development of Core-Shell Polymeric Nanostructures for Delivery of Diagnostic and Chemotherapeutic Agents
Macromolecular complexes of anionic-nonionic block copolymers and cationic antibiotic aminoglycosides have been formed by electrostatic condensation. Amphiphilicity of the complexes was introduced into the shells by incorporating a hydrophobic poly(propylene oxide) segment into the block copolymer. …
