Polyethylenimine, branched (MW 1,800)

Highly branched polyamine with high charge density. Liquid polymers. Soluble in water at all molecular weights, also soluble in lower alcohols, glycols, and THF. Polymers contain primary, secondary, and tertiary amine groups in approximately 25/50/25 ratio.
See poly(2-ethyl-2-oxazoline) for precursors to linear polyethylenimine.
