Linear polyethylenimines (PEIs) contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. The linear PEIs are solids at room temperature where branched PEIs are liquids at all molecular weights. Soluble in hot water, cold water at low pH, methanol, and ethanol. One end of the polymer chain methyl; other end hydroxyl. Contains up to 7-8% of poly(2-ethyl-2-oxazoline) Insouble in: benzene, ethyl ether, acetone and cold water.
