"Rubbery hydrophobic cores" are advantageous over rigid hydrophobic cores, such as crystalline or glassy (as in the case of polystyrene) cores, in that higher loadings of hydrophobic drugs can be carried by the particles with the rubbery hydrophobic cores

Some embodiments are based on a rubbery core, e.g., a poly(propylene sulfide) (PPS) core with an overlayer, e.g., a hydrophilic overlayer, as in PEG, as in the PPS-PEG system recently developed and characterized for systemic (but not targeted or immune) delivery

The rubbery core is in contrast to a substantially rigid core as in a polystyrene or metal nanoparticle system

The term rubbery refers to certain resilient materials besides natural or "synthetic rubbers", with rubbery being a term familiar to those in the polymer arts


For example, cross-linked PPS can be used to form a hydrophobic rubbery core

synthetic rubbers? синтетические каучуки? причем они здесь?
