What are the specifications for Product 21195-U, Polyethyleneimine?
The polyethyleneimine, Supelco 21195-U, is made from Aldrich 181978. Supelco purifies the PEI to use as a GC phase; it is commonly solvated with acetone for use in the manufacturing of packings for gas chromatography columns. It exists as a thick, clear, colorless, odorless liquid at room temperature.
What is the molecular weight of Polyethyleneimine, Product 21195-U?
The molecular weight distribution of the polyethyleneimine: average Mn ~60,000 by gel permeation chromatography (GPC), average Mw ~750,000 by light scattering (ELSD; evaporative light scattering detection).
Do you know the pKa of polyethyleneimine?
The nitrogens in polyethyleneimine (PEI) are mainly in tertiary amines. PEI has a pKa of approximately 5.9.
