Dendritic PIC micelles with bioactive proteins. The invention relates to a Polyion Complex (PIC) polymeric micelle formed by interaction between a bioactive protein and a dendritic block copolymer of opposite charge. The conventional low stability of PIC micelles with bioactive proteins vis-à-vis ionic strength is offset in the present invention by the stability provided by the dendritic block. The overall process for preparing these micelles is facilitated by the simplicity of the drendritic block copolymer synthesis.

The present invention appreciates that compounds comprising nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be reacted with azides using at least radiation energy to initiate the reaction between at least a portion of the compounds and the azides to form membranes that have surprisingly high selectivities for acid gases relative to nonpolar gases such as hydrocarbons. The membranes are also resistant to CO2 plasticization and have high acid gas flux characteristics. The resultant membranes can be extremely thin (e.g., 10 micrometers or less), which promotes high permeability for the acid gas and can translate into high productivity on a scaled-up, industrial level.
