Abstract
The invention pertains to the polymerization of molecules having electrophilic and nucleophilic substituents on the same or different molecules, such polymerization mediated by aminopyridine catalysts which are substantially regenerated during polymerization. The invention also pertains to polymer products of such polymerization, to permselective membranes containing such polymers, and to processes and apparatus for separating fluids.
