Morphologies of PDMS-containing diblock polymers
… of polydimethylsiloxane (PDMS)-containing diblock polymers are investigated as a function of volume fraction, segregation, processing procedure, and temperature. Strongly segregated polyisoprene-PDMS and polystyrene-PDMS diblocks are prepared according to standard procedures in the …

Nanophase separation in monodisperse rodcoil diblock polymers
… self-organization in condensed phases of rodcoil diblock polymers synthesized in our laboratory. Each macromolecule consists of a rigid and monodisperse rodlike segment covalently attached to a flexible coillike segment of narrow molecular weight distribution such that both segments share the same …

Development of Carbohydrate-based Diblock Polymers for Nucleic Acid Delivery
… nucleic acid delivery vehicles based on cationic diblock glycopolymers that contain glucosamine and trehalosamine. Practical procedures were developed to synthesize 2-methacrylamido-2-deoxy glucose and 6-methacrylamido-6-deoxy trehalose starting with commercially available carbohydrates and …

Development of Soft-Matter Delivery Systems: Coupling pH Responsive Polymers to Porous Silica Particles
… In addition to coupling commercially available diblock polymers we synthesized and characterized a unique dual hydrophilic pH responsive diblock copolymer, PEO-PAA. This hybrid polymeric-nanoparticle system drastically improves targeting and release capabilities through the modular ability to …

Synthesis and Characterization of Responsive Poly(Alkyl Methacrylate) Topologies
… and utilized in the synthesis of star-shaped polymers. Star polymer coupling was achieved by reacting the living poly(alkyl methacrylate) using 2,5-dimethyl-2,5-hexanediol dimethacrylate (DHDMA) or dicumyl dimethacrylate (DCDMA). These starshaped polymers were cleaved under hydrolytic …
