Synthesis and Characterization of Novel Polyethers and Polydimethylsiloxanes for Use in Biomaterials
… focuses on the use of novel polyethers and polydimethylsiloxanes in the stabilization of magnetite nanoparticles as well as biomedical applications. The colloidal stabilities of magnetite nanoparticles coated with polyethers containing various functional endgroups were studied. Different …

The synthesis and characterisation of novel long chain dimethyl siloxane surfactants.
… a long, hydrophobic polydimethylsiloxane chain. Polydimethylsiloxanes are low melting materials (glass transition at ca -120°C) with very flexible chains, hence surfactants based on them might be readily soluble in water. This project involves chemical attachment of amphiphilic mesogens to …

Effect of chain structure on the thermodynamics and kinetics of polymer crystallization
… were studied in the case of linear and cyclic polydimethylsiloxanes. An equilibrium melting temperature (T<sub>m</sub>) of 250K was determined by the Hoffman-Weeks extrapolation method for a linear PDMS fraction with <M<sub>n</sub>>=62,700 g/mol. This value is 12°C higher than that previously …

Synthesis, kinetics and supercritical fluid fractionation studies of functional organosiloxanes and their incorporation into segmented copolymers
… and modification of these materials with polydimethylsiloxanes. Tough transparent films were readily solution cast from these materials, which may have potential use as permselective gas separation membranes. Due to the intentionally short segment lengths, evidence of significant amounts …
