ABSTRACT:
This invention relates to the fabrication of a polymeric membrane and a process for utilizing the polymeric membrane for separating components of a feedstream. More particularly, but not by way of limitation, this invention relates to the fabrication of a polymeric membrane and a process for utilizing the polymeric membrane in the separation of aromatics from a hydrocarbon based feedstream. The membranes of the present invention possess low soft segment glass transition temperatures and improved separation characteristics.
