Description

Linear polyethylenimine (L-PEI) is a high-charge cationic polymer that readily binds highly anionic substrates. Industrially, L-PEI can improve the appearance of negatively charged dyes by modulating their properties and improving their adherence to surfaces. L-PEI 100000 contains 7-11% of the acylated amine (N-propionyl) from isomerization-polymerization of 2-ethyl-2-oxazoline followed by acid-hydrolysis of resulting N-propionyl-PEI. For fully deacylated L-PEI, see Polyethylenimine HCl, Linear, Mw 160,000 (L-PEI 160000; Catalog # 25439).
