Synthesis and Characterization of Responsive Poly(Alkyl Methacrylate) Topologies
… synthesized 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 …

Synthesis and Characterization of Well-Defined Poly(1,3-Cyclohexadiene) Homopolymers and Copolymers
Polymers containing poly(1,3-cyclohexadiene) were synthesized using a novel pre-formed initiator comprised of an alkyllithium and a tertiary diamine. The use of a pre-formed intiator at moderate temperatures (25° C) enabled the synthesis of high molecular weight poly(1,3-cyclohexadiene) …

Synthesis and Characterization of Multi-Component Polymeric Materials Prepared via Free Radical Polymerization
High molecular weight star-shaped polystyrenes were prepared via the coupling of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) terminated polystyrene oligomers with divinylbenzene (DVB) in m-xylene at 138 °C. Linear polystyrene oligomers (Mn = 19,300 g/mol, Mw/Mn = 1.10) were synthesized in bulk …

Polyelectrolyte Complexes and their Therapeutic Potential
… into eukaryotic cells in vitro by means of new star-shaped polycations was explored. Second, the structure of ionic multicompartment micelles (MCMs) when complexed with polyions was studied and the performance of these nanostructures as delivery agents of anti-cancer drugs both in vitro and in …

Synthesis and Characterization of Functional Biodegradable Polyesters
… based on Sn(Oct)2 afforded the preparation of star-shaped, poly(D,L-lactide)s (PDLLA)s of controlled molar mass, narrow molar mass distributions, and well-defined chain end functionality. Various modifications of star-shaped PDLLA resulted in macromolecules with tailored functionalities for …
