Synthesis and Aggregation Behavior of Water Soluble Brush-Like Polysiloxanes
Abstract: A series of water soluble brush-like polysiloxane with varying hydrophilic side-chains were syn-thesized by hydrosilylation between 4 kinds of hydride-containing polysiloxanes and unsaturated polyethyleneoxide, and the aggregation behavior was investigated using steady-state fluorescence, dynamic light scattering (DLS), and transmission electron microscopy (TEM). The polysiloxanes with more hydrophilic side-chains would form spherical multipolymer assemblies with a comparatively loose and swollen structure. The density of the hydrophilic side-chains outside the assemblies increased, leading to a solution with improved visible clearness. The obtained relationship between the molecular behavior and the solution characteristics could help design macromolecular systems with expected properties.
